Radar Quizzes & Trivia

There are different types of radar systems. Active radar transmits a signal that is reflected back to the receiver and Passive radar, which depends upon the object sending a signal to the receiver. Test your knowledge on radar systems and functionality by taking the quiz below. Give it your best.
