STARS, the Standard Terminal Automation Replacement System, is built on the UNIX operating system. UNIX is a powerful and versatile operating system known for its stability and security. It is widely used in various industries, including aviation, for its ability to handle large amounts of data and provide reliable performance. STARS, being a critical system for air traffic control, requires a robust and efficient operating system like UNIX to ensure smooth and reliable operations.

UNIX was originally developed in the 1960s by Ken Thompson and Dennis Ritchie at Bell Labs. It was created to provide a multi-tasking and multi-user operating system for a computer game called Space Travel, which simulated the movement of celestial bodies in space. The game required a powerful and efficient operating system to handle the complex calculations and interactions, leading to the development of UNIX.

The kernel is the correct answer because it is the core of the UNIX operating system that controls the hardware resources. It is responsible for managing memory, handling input and output requests, and coordinating the execution of processes. The kernel interacts directly with the hardware and provides an interface for other software components to access the system resources. It is essential for the functioning of the operating system and plays a crucial role in maintaining system stability and security.

Fragment-free forwarding method, also known as runtless switching, is a type of forwarding method in which the switch waits for the first 64 bytes of a frame to be received before forwarding it. This method helps to prevent the forwarding of runt frames, which are frames that are smaller than the minimum Ethernet frame size. By waiting for the first 64 bytes, fragment-free forwarding ensures that the frame is not a runt frame and reduces the likelihood of forwarding corrupted or incomplete frames.

The shell is the correct answer because it acts as a command interpreter and provides a user-friendly interface for interacting with the UNIX operating system. It allows users to execute commands, manage files and directories, and perform various system operations.

When a pulse of radio frequency energy is transmitted, it travels at the speed of light. Radio frequency energy is a form of electromagnetic radiation, and all forms of electromagnetic radiation, including light, travel at the same speed in a vacuum, which is approximately 299,792,458 meters per second. Therefore, the correct answer is the speed of light.

Radio frequency energy travels at the speed of light, which is approximately 299,792,458 meters per second. Since a nautical mile is equal to 1,852 meters, it would take approximately 1.852/299,792,458 seconds for the energy to travel one nautical mile. Multiplying this by 2 gives the time it takes for the energy to travel to the target and return to the radar, which is approximately 12.36 microseconds.

The pulse recurrence time refers to the time interval between the transmission of two consecutive radar pulses. By dividing the time of one radar mile into the pulse recurrence time, we can determine the maximum detection range of a radar. This is because the pulse recurrence time is directly related to the time it takes for the radar signal to travel to the target and back to the radar system, known as the round-trip time. By knowing the pulse recurrence time, we can calculate the distance that the radar signal can travel within that time frame, which gives us the maximum detection range of the radar.

A modem is a device that converts digital data into analog signals so that it can be transmitted over an analog medium, such as telephone lines. The analog carrier refers to the continuous waveform that carries the digital information. This allows the digital data to be transmitted over the analog medium, which is necessary when using traditional telephone lines.

When a radar target is moving towards the radar, it exhibits a higher frequency than the original broadcast. This is known as the Doppler effect. As the target moves towards the radar, the waves are compressed, causing an increase in frequency. This increase in frequency can be detected by the radar system and used to determine the speed and direction of the target.

Analog modems are used over the voice band range of 20 Hz to 20 MHz because this range is capable of transmitting and receiving analog signals. This frequency range allows for the transmission of voice and data signals over telephone lines. Frequencies below 20 Hz are too low for effective communication, while frequencies above 20 MHz are typically reserved for higher frequency applications such as radio and television broadcasting. Therefore, the voice band range of 20 Hz to 20 MHz is the most suitable for analog modems to operate within.

A synchronizer is responsible for ensuring that all circuits connected with the radar operate in a definite timed relationship. It coordinates the timing and synchronization of various components within the radar system, ensuring that they work together seamlessly.

Each workstation serves a specific purpose in the STARS system, such as controlling local airspace, displaying radar and flight data, and managing data communications.

A duplexer is a radar subassembly that allows the radar system to transmit and receive from the same antenna. It is responsible for separating the outgoing and incoming signals, allowing them to be transmitted and received without interference. This component is crucial in radar systems as it enables the system to alternate between transmitting and receiving signals using a single antenna, thereby optimizing the use of resources and ensuring efficient radar operation.

A reciprocal antenna is one that exhibits the same transmit and receive patterns. This means that the antenna will radiate electromagnetic waves in the same way when it is used for transmitting as it does when it is used for receiving signals. In other words, the antenna does not discriminate between transmitting and receiving signals and behaves in a symmetrical manner. This property is important in various applications, such as wireless communication systems, where the antenna's performance needs to be consistent for both transmitting and receiving signals.

Passive feedhorns are used only for receiving signals. Unlike active feedhorns, which can both receive and transmit signals, passive feedhorns are designed solely for the purpose of receiving signals. They do not have any active components or electronics that would allow for signal transmission. Therefore, passive feedhorns are the correct answer for this question.

The distribution of electromagnetic energy from the antenna over the aperture determines the pattern of the antenna. The pattern of the antenna refers to the spatial distribution of the radiated or received electromagnetic energy. It describes how the antenna radiates or receives energy in different directions. By controlling the distribution of energy, the antenna can be designed to have specific radiation characteristics, such as directional or omnidirectional patterns. Therefore, the distribution of energy over the aperture directly influences the pattern of the antenna.

Applications are software programs designed to perform specific tasks. Unlike general software programs, which can perform a wide range of tasks, applications are focused on a particular function or purpose. They are tailored to meet the specific needs of users, whether it is for productivity, communication, entertainment, or any other specific task. Therefore, the correct answer is "Specific".

The shape of the beam of radar energy and its antenna pattern depend on the radar's purpose. Different radar systems are designed for specific purposes, such as air traffic control, weather monitoring, or military surveillance. Each purpose requires a different beam shape and antenna pattern to effectively detect and track the desired targets. Therefore, the purpose of the radar system determines the specific characteristics of the beam and antenna pattern.

The Air Force uses Norton and McAfee as their two anti-virus programs.

The AN/TPS-75 radar set provides information on aircraft for a distance of 240 nautical miles.

The correct answer is Raster. The explanation for this is that a raster scan system uses a thin beam to cover a rectangular area by sweeping the area horizontally with the angle of elevation incrementally stepped up or down with each horizontal sweep of the sector. This scanning method is commonly used in computer monitors and television screens to display images.

Screening is the term used to describe the blocking of all or a portion of the radar beam by an obstacle. When an obstacle comes in the path of the radar beam, it obstructs the transmission and reception of the radar signals, resulting in a loss of signal or a weakened signal. This can affect the accuracy and reliability of the radar system's measurements and detections. Therefore, screening is the correct term to describe this phenomenon.

The purpose of the truck stabilizers when mounting the AN/TPS-75 antenna in the back of a truck is to eliminate the effects of the truck suspension system. This is important because the antenna requires a stable platform to operate effectively. By eliminating the effects of the truck suspension system, the stabilizers ensure that the antenna remains steady and does not experience any unwanted movements or vibrations that could affect its performance.

In a helical scan radar, the antenna rotates on an azimuth sweep while the elevation angle gradually increases from 0° to 90°. This type of scanning allows for a continuous coverage of the surrounding area in a spiral pattern, providing a complete picture of the airspace. The helical scan radar is particularly useful in applications where a wide coverage area is required, such as air traffic control or weather monitoring.

Near-simultaneous reception of pulse-type information causes delayed, but separate, pulses. This means that the pulses are received in close succession, but with a slight delay between each pulse. This could be due to factors such as the distance between the transmitter and receiver, the speed of the electromagnetic waves, or any obstacles or interference that the waves encounter along their path. As a result, the pulses arrive at the receiving antenna at slightly different times, causing the delay in their reception.

A radar system that uses a B-scan indicator is typically used for precision approach. Precision approach radar systems are designed to provide accurate and detailed information about the position and movement of aircraft during the final stages of landing. The B-scan indicator is a display feature that shows a cross-sectional view of the radar echoes, allowing for precise measurement of the aircraft's altitude and alignment with the runway. This type of radar system is crucial for ensuring safe and accurate landings, especially in low visibility conditions.

The AN/TPS-75 radar set uses a slotted waveguide antenna. A slotted waveguide antenna consists of a rectangular waveguide with slots cut into the broad walls. These slots allow electromagnetic waves to radiate from the waveguide, creating a beam of radiation. This type of antenna is commonly used in radar systems due to its ability to provide a narrow beamwidth and high gain, allowing for accurate and long-range detection and tracking of targets.

A plan-position indicator (PPI) provides information about the range and azimuth of a target. The range indicates the distance between the radar and the target, while the azimuth indicates the target's position in relation to the radar's reference point. By displaying both range and azimuth, the PPI can provide a comprehensive view of the target's location and movement in a two-dimensional plane.

The correct answer is 5. The AN/TPS-75 radar provides the operator with 5 modes of communication through its communications system.

In a typical indicator system, the digital display data from the data processing circuits is converted into analog drive signals in the deflection circuits. The deflection circuits control the movement of the cathode-ray tube's electron beam, which creates the visual display on the screen. By converting the digital data into analog signals, the deflection circuits can accurately position the electron beam to create the desired image on the screen.

The vacuum in a cathode-ray tube (CRT) prevents collisions between electrons in the beam and air molecules. When the CRT is in operation, an electron beam is produced and accelerated towards the screen. If there was air or any other gas present inside the tube, the electrons would collide with the gas molecules, causing scattering and loss of energy. This would result in a distorted image on the screen. By creating a vacuum inside the CRT, the path of the electrons remains unobstructed, allowing them to travel in a straight line and accurately hit the phosphor coating on the screen, producing a clear and focused image.

The correct answer is 32 MHz. This means that the frequency of the master clock signal provided by the frequency generator to the processor timing generator in the AN/TPS-75 radar is 32 MHz.

IFF/SIF interrogations use a frequency of 1030 MHz. This frequency is commonly used in aviation for the purpose of identifying friendly aircraft and distinguishing them from potential threats. It allows for communication between aircraft and ground-based radar systems, enabling the exchange of identification codes and other crucial information. The use of 1030 MHz frequency ensures efficient and reliable identification of friend or foe during military operations and air traffic control.

The AN/UPM-155 radar test set can be operated with either a 115 VAC or a 230 VAC input voltage. This means that it can be supplied with either 115 VAC or 230 VAC for its operation.

The AN/TPS-75 transmitter's driver circuit produces a 2.7 kW peak radio frequency (RF) pulse as its final output. This means that the circuit generates a high-powered pulse of radio frequency energy with a peak power of 2.7 kW. This pulse is likely used for transmitting signals over long distances or for radar applications where a strong RF signal is required. The other options mentioned in the question (such as +320 VAC carrier and +28 volt video pulse) are not the final output of the driver circuit.

The bandwidth required for double-sideband emitted carrier (DSBEC) amplitude modulation (AM) is twice the modulating bandwidth. This means that the bandwidth needed to transmit the DSBEC signal is double the bandwidth of the original modulating signal. This is because DSBEC AM includes both the upper and lower sidebands, which effectively doubles the required bandwidth.

A Twystron is used as the final power amplifier in the AN/TPS-75. A Twystron is a type of vacuum tube that is capable of generating high power levels. It is commonly used in radar systems, such as the AN/TPS-75, to amplify the signals before they are transmitted. The Twystron provides the necessary power boost to ensure that the radar signals have sufficient strength and range.

The maximum asynchronous data rate for the Defense Red Switch Network (DRSN) is 19.2 Kbps.

Non-uniform quantizing and companding decreases the length of a code word from 11 to 7 bits. This means that the original code word, which was represented by 11 bits, is now compressed and represented by only 7 bits. This compression is achieved through the process of quantizing, which reduces the number of possible values that can be represented, and companding, which further compresses the range of values. The result is a more efficient representation of the original code word, with a shorter length.

Synchronous transmission reduces the overhead costs of data transmission by blocking many characters together for transmission. This means that multiple characters are sent as a single unit, reducing the number of start and stop bits needed for each character. By reducing the number of control bits required, more message data can be sent in a shorter amount of time, resulting in lower overhead costs.

The AN/TPS-75 waveguide is pressurized and dehydrated to keep out moisture and prevent arcing. Pressurizing the waveguide helps to create a dry environment inside, preventing moisture from entering and causing damage to the equipment. Dehydrating the waveguide further ensures that any existing moisture is removed. Additionally, preventing arcing is important as it can cause electrical discharge and damage the waveguide. By keeping out moisture and preventing arcing, the waveguide can function effectively and maintain its performance.

The amount of 1's in a data bit pattern during a vertical redundancy check determines the parity. Parity is a method used to detect errors in data transmission. It involves adding an extra bit to the data to make the total number of 1's either even or odd. By comparing the number of 1's in the received data with the expected parity, errors can be detected.

A desiccant canister is used to dehydrate the AN/TPS-75 waveguide air. Desiccants are substances that have a high affinity for water vapor and are commonly used to remove moisture from the air. The canister contains a desiccant material that absorbs the moisture present in the waveguide air, preventing it from causing any damage or interference to the equipment. This ensures that the waveguide air remains dry and free from moisture, allowing for optimal performance of the AN/TPS-75 system.

The AN/TPS-75 antenna uses 22 out of the 48 slotted sticks for transmitting.

Fiber optic cables are not affected by electromagnetic fields. This is because they use light signals to transmit data, rather than electrical signals. Unlike copper-based cables, which can be affected by electromagnetic interference, fiber optic cables are immune to such interference. This makes them more reliable and less susceptible to disruptions in signal quality.

An uninvestigated or unevaluated occurrence that potentially jeopardizes the security of COMSEC material and the secure transmission of government information is best described as a COMSEC incident.

The sensitivity time control (STC) interface is responsible for dynamically varying the gain of the AN/TPS-75's intermediate frequency (IF) receivers. This means that the STC interface adjusts the gain of the receivers based on the sensitivity time control settings, allowing for optimal reception of radar signals. The other options mentioned, such as the step attenuator, frequency generator, and radar control microprocessor, do not have the specific function of dynamically varying the gain of the IF receivers.

A loose tube buffer allows the fiber optic cable to be twisted or pulled with little stress on the fiber. In a loose tube design, the fiber is placed inside a flexible tube that provides protection and allows for movement. This design allows the cable to withstand external forces, such as twisting or pulling, without putting excessive stress on the fiber. This flexibility is especially important in installations where the cable may be subject to frequent movement or environmental stresses.

Fiber optic links use infrared light because it has a longer wavelength and can travel long distances without significant loss of signal. The frequency range of 750 to 1500 nm falls within the infrared spectrum, making it suitable for transmitting data through fiber optic cables. The other options, 400 to 750 nm and 400 to 750 mm, are not within the correct frequency range for fiber optic links.

Imperfections in an optical fiber's basic structure cause scattering. Scattering refers to the phenomenon where light rays traveling through the fiber get redirected in different directions due to these imperfections. This can result in the loss of signal strength and degradation of the transmitted data.

The most useful way to classify fiber optic cable is by considering its refractive index profile and the number of modes it supports. The refractive index profile determines how light propagates through the fiber, while the number of modes refers to the number of different paths that light can take within the fiber. These characteristics are crucial in determining the performance and capabilities of the fiber optic cable, making them the most relevant factors for classification.

The transition of data between the real-time and the processing-time circuits in the AN/TPS-75 radar target data post processing function takes place in the first-in first-out (FIFO) buffer. This buffer acts as a temporary storage area for the data, allowing it to be transferred from the real-time circuit to the processing-time circuit in an organized and sequential manner. By using a FIFO buffer, the radar system can ensure that the data is processed in the correct order, preventing any loss or corruption of information.

The height between two targets is referred to as the relative height because it indicates the vertical distance between the two points in relation to each other. It is a measure of the height difference between the targets, regardless of their absolute height or position. The term "relative" implies that the height is being considered in comparison to something else, in this case, the height of the other target.

The rotary switch is used to select various measurement functions on the Fluke 8025A multimeter. This switch allows the user to easily switch between different modes, such as voltage, current, resistance, and continuity. By turning the rotary switch to the desired function, the user can quickly and accurately measure different electrical quantities.

The correct answer is read-only memory (ROM). ROM is a type of storage that stores program instructions permanently. It is non-volatile, meaning the data is not lost when the power is turned off. In the case of the AN/UYQ-27, which is a computer system used in military applications, it makes sense to use ROM for program instructions as it provides a secure and reliable storage medium that cannot be easily altered or tampered with.

To measure 250 milliamps alternating current (AC) on the Fluke 8025A, you would select the "Milliamps/amp AC" current range. This range is specifically designed to measure AC current in milliamps, making it the appropriate choice for this measurement.

The correct answer is Modular control equipment interface group (MIG). The MIG in the AN/TPS-75 radar system is responsible for transmitting target track reports to the AN/TYQ-23 operations module (OM). The MIG acts as an interface between the radar system and the OM, allowing for the transfer of important information such as target track reports. It ensures smooth communication and coordination between the radar system and the operations module, enabling effective tracking and monitoring of targets.

Low-insulation resistance between conductors can cause high-attenuation, crosstalk, and noise. When the insulation resistance is low, it means that there is a leakage of current between the conductors. This leakage can lead to the attenuation of the signal, causing it to weaken or lose strength. Additionally, the leakage current can interfere with other nearby conductors, resulting in crosstalk, where signals from one conductor are unintentionally picked up by another. This can introduce unwanted noise into the system, further degrading the signal quality.

The MCE interface electronics (MIE) unit within the modular control equipment interface group (MIG) provides identification friend or foe/selective identification feature (IFF/SIF) target detection and extraction for the AN/TPS-75 radar system. This unit is responsible for processing and interpreting the signals received from the radar system to identify and classify targets as friend or foe. It plays a crucial role in enhancing the situational awareness and decision-making capabilities of the radar system operators.

The correct answer states that when using the AN/PSM-2 megger, the correct way to apply the regulated output voltage is to turn the hand-crank at a rate to keep the indicator lights at a steady glow. This implies that the indicator lights on the megger are used as a reference to determine the correct voltage output. By keeping the lights at a steady glow, it ensures that the voltage is regulated and maintained at the desired level.

The MCE interface electronics (MIE) is located in A1, the upper half of the modular control equipment interface group (MIG) in the AN/TPS-75. This unit is responsible for interfacing the control equipment with other components of the radar system. It likely plays a crucial role in the overall functionality and operation of the radar system.

The primary purpose of the ISLS control monitor in the AN/TPS-75 radar's IFF/SIF system is to provide side-lobe suppression. This means that it helps to reduce or eliminate the interference caused by side lobes, which are unwanted radiation patterns that can interfere with the main radar beam. By suppressing these side lobes, the radar can improve its accuracy and target detection capabilities.

An earth ground tester typically uses 3 probes. These probes are used to measure the resistance between the ground and the earth electrode, ensuring that the grounding system is functioning properly.

The area of a digital storage oscilloscope that takes digitized samples and performs numerous manipulations on the data including measuring rise and fall times, periods, time intervals, and math computations is the microprocessors.

A digital storage oscilloscope normally uses real-time sampling on single-shot or seldom-occurring signals. Real-time sampling means that the oscilloscope captures and displays the waveform as it occurs in real-time, allowing for accurate representation of the signal's shape and timing. This type of sampling is essential for capturing and analyzing transient or infrequent events. Sequential sampling, on the other hand, captures and stores samples one after another, which may not accurately represent the original signal. Repetitive sampling is used for signals that repeat regularly, and random sampling is not suitable for capturing single-shot or seldom-occurring signals.

The frequency range of an audio signal generator is typically between 20 Hz and 20 kHz. This range covers the audible frequencies that humans can hear, with 20 Hz being the lowest frequency and 20 kHz being the highest frequency. Audio signal generators are commonly used in audio testing and equipment calibration.

Aligning galvanometers is not an application of a radio frequency generator. A radio frequency generator is used for tasks such as verifying transmitter frequencies, troubleshooting receivers, and checking antenna systems. However, aligning galvanometers is a separate task that involves adjusting and calibrating the position of galvanometers, which are devices used to measure small electrical currents. This task does not require the use of a radio frequency generator.

The crossed-field amplifier is a type of amplifier that utilizes a crossed electric and magnetic field to achieve high power amplification. It is commonly used in applications where high power and efficiency are required, such as in radar systems.

The scanning method used by the radar system refers to the motion of the antenna axis (of the beam) as the radar looks for an aircraft. This means that the radar system moves the antenna in a specific pattern or direction in order to scan the surrounding area for any aircraft. By moving the antenna, the radar system can cover a larger area and detect any objects within its range. This scanning method allows the radar system to effectively search for aircraft and track their movements.

The correct answer is Coder-synchronizer. A Coder-synchronizer is an AN/TPX-42A air traffic control component that generates mode interrogation triggers. This component is responsible for encoding and decoding signals to determine the identity of aircraft in the airspace. It synchronizes the timing and encoding of the signals to ensure accurate and reliable communication between the air traffic control system and the aircraft.

A wide area network (WAN) is the correct answer because it connects networks that are typically separated by geographical distances between cities, states, countries, or around the world. Unlike a local area network (LAN) which connects devices within a limited area such as a home or office, a WAN allows for communication over larger distances. A virtual private network (VPN) is a technology that creates a secure connection over a public network, and a metropolitan area network (MAN) connects networks within a specific geographic area such as a city.

Installing the PAR at a position where it gives the best coverage to the most important runway would be the best location. This ensures that the radar system provides optimal coverage for the runway that is of highest priority or significance.

The AN/GPN-20 airport surveillance radar (ASR) provides emergency obstruction light operation for a minimum of 10 minutes. This means that in the event of an emergency or power outage, the radar system will continue to provide obstruction lighting for at least 10 minutes, ensuring the safety of aircraft and other objects in the vicinity of the airport. This feature is crucial in maintaining visibility and preventing accidents during critical situations.

The second line in the 2-line character block on the OD-153 airport surveillance radar (ASR) indicator represents the reported altitude in hundreds of feet. This means that the three decimal digits on the second line indicate the altitude of the tracked aircraft, with each digit representing a hundred feet.

Cyclic redundancy is an error detection method that is commonly used for checking data blocks greater than 512 and is about 99% effective in most applications. It involves generating a checksum by performing a mathematical calculation on the data block and appending it to the block. The receiver can then perform the same calculation on the received data and compare it with the appended checksum to detect any errors. This method is widely used in communication protocols and storage systems to ensure data integrity.

The AN/GPN-22 precision approach radar (PAR) emergency power is supplied by a 12-volt, direct current (VDC) battery. This means that the radar system can be powered by a battery that provides a constant 12 volts of direct current. This type of battery is commonly used in many electronic devices and systems as it provides a stable and reliable power source. The use of direct current ensures that the power is flowing consistently in one direction, which is important for the proper functioning of the radar system.

The low-altitude alerting system in the programmable indicator data processor (PIDP) II is responsible for notifying the operator when a tracked target enters one of the 1,024 geographic sectors and is at or below the altitude set for that sector.
