    What is the correct order in which the four radars in an air defense network are used?

    • Early warning, height finder, acquisition, and terminal defense.

    • Height finder, early warning, acquisition, and terminal defense.

    • Acquisition, early warning, height finder, and terminal defense.

    • Acquisition, height finder, early warning, and terminal defense

    Correct Answer
    A. Early warning, height finder, acquisition, and terminal defense.
    Explanation
    The correct order in which the four radars in an air defense network are used is as follows: early warning, height finder, acquisition, and terminal defense. This order makes sense as the early warning radar is responsible for detecting incoming threats at long ranges, the height finder radar determines the altitude of the detected targets, the acquisition radar tracks and identifies the targets, and finally, the terminal defense radar engages and neutralizes the threats.

    Additions to the C2 network extend the range of the air defense system?

    • Computers and AAA.

    • Long-range interceptors and computers.

    • AWACS and AAA.

    • Long-range interceptors and AWACS.

    Correct Answer
    A. Long-range interceptors and AWACS.
    Explanation
    Long-range interceptors and AWACS are the correct additions to the C2 network to extend the range of the air defense system. Long-range interceptors are capable of engaging targets at a greater distance, while AWACS (Airborne Warning and Control System) provides airborne surveillance and command and control capabilities, enhancing the overall effectiveness and coverage of the air defense system. The combination of these two additions allows for a wider range of detection, tracking, and interception capabilities, making it the most suitable choice for extending the range of the air defense system.

    What component of the RWR identifies radar signals?

    • Antenna.

    • Signal processor.

    • Control indicator.

    • Receiver/amplifier

    Correct Answer
    A. Signal processor.
    Explanation
    The signal processor is the component of the RWR that identifies radar signals. It processes the received signals from the antenna and analyzes them to determine if they are radar signals. The signal processor is responsible for detecting, classifying, and tracking radar signals, allowing the RWR to provide accurate information about potential threats.

    What is the emissivity factor of a theoretical black body?

    • 0.5.

    • 0.8.

    • 1.0.

    • 1.2.

    Correct Answer
    A. 1.0.
    Explanation
    The emissivity factor of a theoretical black body is 1.0. A black body is an idealized object that absorbs and emits all radiation that falls onto it. It is a perfect emitter and absorber of radiation at all wavelengths. The emissivity factor is a measure of how efficiently an object emits radiation compared to a black body. A value of 1.0 means that the object emits radiation just as efficiently as a black body, making it a perfect emitter.

    When a photon causes the release of another photon, it is called

    • Stimulated emission.

    • Population inversion.

    • Spontaneous emission.

    • Population conversion.

    Correct Answer
    A. Stimulated emission.
    Explanation
    When a photon stimulates the release of another photon, it is known as stimulated emission. This process occurs when an excited atom or molecule is hit by a photon of the same energy, causing it to release a second photon with the same energy, phase, and direction. This is a fundamental principle in the operation of lasers, where stimulated emission is used to amplify light and generate a coherent beam.

    What region of the frequency spectrum is Air Force aircraft laser sensors used?

    • Radio.

    • Infrared.

    • Ultraviolet.

    • Visible light.

    Correct Answer
    A. Infrared.
    Explanation
    Air Force aircraft laser sensors are used in the infrared region of the frequency spectrum. Infrared light has longer wavelengths than visible light and is able to detect heat signatures emitted by objects. This makes it useful for military applications such as detecting enemy aircraft or missiles. Infrared sensors are also used for night vision technology, allowing pilots to see in low light or dark conditions.

    A nonlinear device is any electronic device where the

    • Impedance remains constant when the voltage changes.

    • Impedance remains constant when the current changes.

    • Current through the device is proportional to the applied voltage.

    • Current through the device is not proportional to the applied voltage.

    Correct Answer
    A. Current through the device is not proportional to the applied voltage.
    Explanation
    A nonlinear device is characterized by the fact that the current through the device is not directly proportional to the applied voltage. In other words, as the voltage changes, the current does not change in a linear manner. This means that the impedance of the device does not remain constant as the voltage changes. Nonlinear devices often exhibit behaviors such as saturation, where the current reaches a maximum value even if the voltage continues to increase, or hysteresis, where the current depends not only on the current voltage but also on its history.
