摘要:

提出一种针对波形捷变合成孔径雷达(synthetic aperture radar, SAR)的新型干扰方法。借鉴间歇采样原理,结合快时间、慢时间调制,形成新型欺骗干扰。利用间歇采样实现在波形捷变SAR当前脉冲内及时转发,利用快时间调制实现距离向迁移,利用慢时间调制实现方位向上的多假目标。该新型干扰为实现对波形捷变SAR有效干扰提供了一种全新的途径。仿真实验验证了该干扰方法的可行性和有效性。

Abstract:

A new method of jamming against waveform agile synthetic aperture radar (SAR) is proposed: the intermittent sampling decoy jamming. This jamming can form multi-false targets series through modulation in fast or slow time domain, in which the intermittent sampling repeater jamming can be applied to the waveform agile SAR pulses in time. And this jamming may realize electronic countermeasure (ECM) against waveform agile SAR. The jamming provides a new feasible approach against waveform agile SAR. The theoretical feasibility and validity are proved by simulation experiments.
