2/23/2009 3 GTRI_B-7 Copyright by Georgia Tech Research Corporation, 2009 (Very) Brief History of RWR RWRs have been around for about 40 years. First-generation RWRs were used by the US Air Force during the Vietnam War in response to Russian radar- guided SAMs deployed in North Vietnam. The Israelis suffered heavy losses to radar-directed AAA and SAMs during the 1973 Yom Kippur War. GTRI_B-8 Copyright by Georgia Tech Research Corporation, 2009 Example USAF RWR Installations RWR Type Aircraft ALR-56C F-15 ALR-56M F-16, C-130, B-1 ALR-69 B-52, A-10, C-130, F-16, C-130 ALR-94 F-22 APR-39 C-130, V-22 GTRI_B-9 Copyright by Georgia Tech Research Corporation, 2009 How Does an RWR Work? Hardware handles detection Hardware detects radar pulses and converts pulse parameters to digital format Major hardware components: antennas, RF cables, receiver, signal processor, user I/O devices Software handles identification and aircrew interface Software processes digital data to determine what type of radar system is illuminating the aircraft and then provides aircrew cues Major software components: operational flight program and mission data file
