Information on Identification Friend or Foe

The identification friend or foe (Identification Friend or Foe) 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.
