What are the components of secondary radar?

The components of secondary radar include an interrogator, antenna, transponder, receiver, and radar display, making this choice the most comprehensive.

An interrogator is responsible for sending out a signal to initiate communication with transponders in aircraft. The antenna is crucial for both transmitting the interrogator's signals and receiving responses from the transponders. The transponder is contained within the aircraft and responds to the interrogator's signal by sending back information, such as the aircraft's identification and altitude. The receiver captures these responses, allowing the radar system to gather crucial data about the aircraft’s position and altitude. Finally, the radar display visually represents this information for air traffic controllers.

This combination of components works together to enhance air traffic control by providing precise information about the location and status of aircraft in the sky, which is essential for safety and efficient airspace management.
