Radar ECCM Techniques

ECM systems incorporating repeater, transponder and noise jamming techniques can produce a plethora of extraneous false targets which then give rise to bogus target track files. False target detections and subsequent false tracks can so overload a radar's processing hardware/software that the normal functioning of the system can be brought to a virtual standstill. The goal of this Phase I SBIR program is to develop and investigate novel ECCM techniques to detect and eliminate ECM noise, repeater and transponder signals from radar track files. To accomplish this goal, we have selected an approach which exploits the shortcomings of conventional techniques for ECM signal generation. In particular, a radar modulation technique is proposed which can conceptually defeat digital RF memory (DRFM) and nonlinear amplifier devices used in ECM systems.
