Overview[]
The Electronic Warfare Integrated Reprogramming program (EWIR) supported the development of automatic signal recognition equipment that informed pilots of the radars that were illuminating the aircraft, and alerted them if threat-associated radars, such as surface-to-air missile radars were tracking the aircraft.
The data base of assessed information was needed to permit the "Reprogramming community" to program likely parameters of the suspected but undetected wartime-only signal modes into the automatic signal recognizers of the Air Force's radar warning receivers. Because these receivers were installed in every combat and combat-support aircraft in the U.S. Air Force inventory, it was imperative that they contain the best possible information to permit unfailing recognition — during combat — of all modes of threat radar signals.
