在分析SAR对点目标回波、分布式地物杂波和噪声处理特点的基础上,总结了对SAR有源电子干扰的特点,给出了对设计SAR对抗系统有指导意义的结论。应用信号叠加的方法进行了仿真,验证了基于干扰等效后向散射系数统计特性分析的干扰效果评价方法。

Based on processing characteristic analyses of point target's echo signal,distributed target's clutter,and noise in SAR,characteristic of Electronic Counter Measures(ECM) and constructive conclusions on EA systems against SAR are presented.By using a signal superposition simulation method,simulations results are presented,which verified the jamming effect evaluation based on jamming equivalent backscatter coefficients measure.
