摘　　要：合成孔径时间内每个回波信号进行固定频移只能产生一个虚假目标;当去除脉间的相关特性时会产生一条干扰线。针对这一局限,文中对随机移频干扰进行了探讨。阐述了随机移频干扰的原理,分析了干扰的效果。并采用实验仿真与干扰图像评估数据相结合的方法,验证了干扰方法的有效性和优越性。Fixed frequency-shift jamming only can produce a fake target,and wiping off the coherent between the jamming signals results in a jamming line.With this limitation in consideration,the paper discusses the random frequency shift jamming.The jamming principle is introduced first,followed by an analysis of the jamming effect,and finally by combining the jamming effect evaluation,the simulation substantiates the advantage and validity.
