摘要

摘要: 论文针对多通道SAR-GMTI提出一种新的二维欺骗干扰方法，该方法通过对截获的SAR信号进行距离向余弦调相的同时，利用干扰机转动实现方位向余弦调相，可对多通道SAR-GMTI实现二维余弦调相转发欺骗干扰效果，并采用三通道干涉对消方法分析了其对GMTI的对抗性能，该方法对SAR和多通道SAR-GMTI均可产生2维网状多假目标干扰效果，可同时保护地面运动目标和静止目标。理论分析和仿真实验验证了该干扰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.
