摘要
Abstract
A new cancellation method processed at the superposition of equivalent phase center (EPC) is proposed to suppress deception jamming against multiple-input multiple-output synthetic aperture radar (MIMO-SAR) .MIMO-SAR employs co-located antennas in azimuth direction and transmits multiple linear frequency modulation (LFM) signals with step carrier frequency to form crossed EPC, where the echo pairs have the equal delay and different carrier phase. The deception jamming can be eliminated by cancellation processing at each superposition of EPC. Geometry model of MIMO-SAR with co-located antennas is given. The radar echo with deception jamming is analyzed. The difference between deception jamming signal pair at each superposition of EPC and cancellation procedure are discussed.The simulation experiments are performed to validate the proposed method.关键词
