What are the two main types of radar systems?

The correct answer identifies the two main types of radar systems as primary and secondary. Primary radar operates by sending out radio waves which bounce off objects, such as aircraft, and return to the radar system. The information gained from the return signal helps in determining the range, bearing, and speed of the detected objects. This type of radar does not rely on any equipment onboard the aircraft and can track any object that reflects radio waves. Secondary radar, on the other hand, relies on signals transmitted from the aircraft itself. It involves a transponder within the airplane that responds to interrogations from the radar system by transmitting information such as the aircraft's identification and altitude. This type of radar is essential for enhancing situational awareness and managing air traffic more efficiently, especially in controlled airspace. Understanding the differences between these two types of radar is fundamental for air traffic control, as both play critical roles in tracking and managing aircraft during flight.
