SAR二维间歇采样转发散射波干扰研究

摘要

A new method of SAR 2-D interrupted sampling repeater scatter-wave jamming is proposed. The jammer interruptedly samples the received SAR signal, and transmits interrupted-sampling SAR signal to ground. This jamming takes advantages of both the 2-D interrupted sampling jamming which can form multi-false targets, and the scatter-wave jamming which can make the jamming echo take the real targets' scattering information. This jamming method can realize two-dimensional jamming in range arid azimuth, and cause the SAR image ambiguous. Its validities are proved by simulation.%提出一种合成孔径雷达(synthetic aperture radar,SAR)二维间歇采样转发散射波干扰方法:即干扰机接收到SAR发射的信号,在距离向和方位向上二维间歇采样后发射到地面,散射后被SAR系统接收.该方法将SAR间歇采样转发干扰同散射波干扰相结合,利用间歇采样转发干扰实现多假目标干扰,再通过散射波干扰使干扰回波携带真实的散射信息,兼具二维间歇采样干扰和散射波干扰的优点.仿真实验验证了该方法的有效性.
