Radar — IFF
Information on IFF
The identification friend or foe (IFF) system is an
example of a secondary radar system that is in wide
use in the military environment.
A secondary radar system is a
cooperative target identification system in which the interrogator transmits an
encoded signal to a target. The signal transmitted by the
secondary radar is intercepted and received by the target. The
target has a transponder on board that interprets the encoded
signal and transmits an encoded reply back to the interrogator.
The secondary radar system receives and interprets the target's encoded
signal.
