EMI/EMC effects on EW receiver systems of Military aircraft

All Electronic Warfare (EW) systems must be able to operate in the crowded electromagnetic environment in the war scenario. The advanced features in modern EW systems demand extensive test and evaluation to provide defined operational performance. Different transmitters used in Military aircraft create electromagnetic interference/coupling to other systems used in the aircraft. Performance will be degraded due to electromagnetic interference/coupling in highly sensitive wide band EW receivers used in Military aircraft, The Airborne systems like Radars, Electronic Counter Measure systems (ECM), Communication and Control systems involved in Military aircraft, their radiation spectrum and EMC effects on EW receiver will be presented in this paper.
