Radar special evaluation report: Degradation of AN/UPX-6 interrogator set identification friend or foe/selective identification feature IFF/SIF returns from F-4 and RF-4 aircraft
Abstract
This report concerns the degraded identification friend or foe/selective identification feature (IFF/SIF) returns received from F-4 and RF-4 aircraft by radar facilities using the AN/UPX-6 interrogator set. The specific system investigated was an AN/MPN-13 mobile ground control approach facility. The primary cause of the degradation was that the alignment of the KY-532B/ASQ airborne transponders in the subject aircraft was not compatible with the interrogation pulses transmitted by the AN/UPX-6.
