摘　　要：根据SAR散射波干扰的原理,讨论了干扰点目标和面目标生成的算法,并依据距离徙动准则和聚焦深度准则分析了虚假图像欺骗干扰和散焦图像压制干扰效果,最后通过计算机仿真对不同的干扰效果进行了验证,说明了SAR散射波干扰是一种有效的干扰方式。The algorithm of generation of dot jamming target and plane jamming target are discussed, based on the principle of scatter-wave jamming to SAR. The effects of false image deceptive jamming and unfocused image suppression jamming are analyzed, based on the rules of range migration and focusing profundity. And the effects are validated by simulations which show that scatter-wave jamming is an effective jamming method.
