Secondary Surveillance Radar (SSR) - is a radar system wherein a radio signal transmitted by a ground interrogator initiates the transmission of a radio signal from an airborne transponder. With SSR additional information maybe fed into the radarscope such as the identification of the aircraft, its altitude and ground speed in knots.

Transponder is a ground-based receiver/transmitter, which receives a radio signal from an aircraft and transmits it back to the aircraft.
