SAR二维间歇采样转发干扰研究

摘要

提出了一种合成孔径雷达（SAR）干扰方法：SAR二维间歇采样转发干扰。给出了干扰的基本原理和干扰信号模型。该方法通过转发二维间歇采样后的SAR信号,使得SAR回波在距离向频域和方位向多普勒域成对扩展,实现了对SAR的多假目标干扰,而且干扰同时具有欺骗和压制的双重特征。仿真实验验证了该方法的有效性。%A new kind of SAR jamming method,2-D interrupted-sampling repeater jamming,is proposed.The fundamentals and implement of this method are investigated.This method makes SAR echo extend both in range frequency domain and azimuth Doppler domain via 2-D interrupted-sampling repeater,and achieves the effect of multi-false targets.Both the suppression and deceptiveness exist in this method.Its validities are proved by the simulation.
