The problem addressed is effective self protection for close air support helicopters and special electronic mission (SEMA) standoff aircraft. The approach is generic radar "signature" assessment and correlation emitter sort, statistical estimate prediction of center fr equency and time of arrival, and, parameter measurement of modern "agile-agile" and coherent waveforms. The solution is implemented with soa technology in surface acoustic wave (SAW) devices, multiocave microwave devices and high speed digital microprocessors. An eingineering development "flyable test box" is proposed for initial laboratory demonstration and subsequent flight demonstration as part of developing esm/rwr/ecm systems such as medfli and scarecrow. The "test box" is to specifically demonstrate: monopulse "signature sort" in a dense, complex environment, center frequency accuracy for "agile-agile" and coherent waveforms, waveform parameter resolution and measurement accuracy
