摘要: 提出一种新的合成孔径雷达(SAR)干扰方法:SAR间歇采样散射波干扰。将间歇采样转发干扰和散射波干扰结合, 实现携带真实目标散射信息的多假目标干扰。间歇采样转发干扰能实现在波形捷变SAR当前脉冲内及时转发进行对抗,而散射波干扰携带真实目标在方位向的多普勒调制散射信息。本方法将两者的优势结合,使干扰具备对抗波形捷变SAR的潜力,是一种巧妙的干扰样式。这为实现对波形捷变SAR干扰提供了一种可行的途径。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 SAR jamming, the intermittent sampling scatter-wave jamming is proposed. This jamming can form multi-false vivid target scene series which take the real targets’ all scattering information, for it takes advantages of both intermittent sampling repeater jamming and scatter-wave jamming. The intermittent sampling repeater jamming can produce multi-false targets in the waveform agile SAR current pulses. As a clever jamming mode, this jamming may realize electronic counter measure (ECM) against waveform agile SAR in time. And the scatter-wave jamming can make the jamming take the real targets’ scattering information and form Doppler modulation in azimuth. So the jamming provides a new feasible approach against waveform agile SAR. The theoretical feasibility and validity of the method are proved by simulation experiments.

Key words: SAR, Intermittent sampling, Electronic counter measure(ECM), Scatter-wave jamming, Waveform aGile
