Abstract
An IFF interrogation system for use on an aircraft is described. The system transmits a signal from an interrogator to a transponder and from the transponder to the interrogator. The system includes a non-reciprocal IFF antenna that breaks either an uplink signal or a downlink signal at any given angle outside the main beam. The IFF transmitter transmits an Uplink Σ signal and an Uplink Δ signal to the IFF antenna.
