secondary surveillance radar
航空 A surveillance radar system which uses transmitters/receivers interrogators and transponders. (The requirements for interrogators and transponders are specified in Chapter 3.)
航空, 加拿大 A radar system that requires complementary aircraft equipment transponder. The transponder generates a coded reply signal in response to transmissions from the ground station interrogator. Since this system relies on transponder-generated signals rather than signals reflected from the aircraft, as in primary surveillance radar, it offers significant operational advantages such as increased range and positive identification.
