摘要

摘要: 論文針對多通道SAR-GMTI提出一種新的二維欺騙干擾方法，該方法通過對截獲的SAR信號進行距離向余弦調相的同時，利用干擾機轉動實現方位向余弦調相，可對多通道SAR-GMTI實現二維余弦調相轉發(fā)欺騙干擾效果，并采用三通道干涉對消方法分析了其對GMTI的對抗性能，該方法對SAR和多通道SAR-GMTI均可產生2維網狀多假目標干擾效果，可同時保護地面運動目標和靜止目標。理論分析和仿真實驗驗證了該干擾方法的可行性和有效性。

Abstract: A new deception jamming method for multi-channel SAR-GMTI is studied. The SAR signal received by jammer is modulated by cosinusoidal phase in the range, and is modulated by cosinusoidal phase in the azimuth based on the jammers rotation motion, so deception jamming performance of 2-D cosinusoidal phase can be realized at the same time. The countering performance against GMTI is analyzed by using the tri-channel interference cancelling technique. The method can produce 2-D netted multi-false targets jamming performance, so the ground moving targets and stationary targets can be protected at the same time. Theoretical analysis and computer simulation justify the validity and the efficiency of the proposed method.
