摘　　要：为了形成对线性调频(LFM)脉压雷达的压制干扰效果,研究了LFM脉压雷达调频斜率微调和余弦调相两种调频斜率失配干扰方法,进行了仿真.根据调频斜率微调干扰实现覆盖干扰的结果,分析了余弦调相实现多假目标干扰的原理以及各假目标间距和幅度特性.仿真结果验证了理论分析的正确性.For purpose of generating the suppressing and jamming of LFM pulse compression radar, this paper studies two sorts of FM slope mismatch jamming methods including the FM frequency slope trimming and cosine phase modulation, and simulates on them. By the results of implementing the coverage jamming over the FM slope jamming, the principles of using the cosine phase modulation to jam the multiple false targets and the interval between each false target as well as their amplitude characteristics are analyzed, and the simulation results prove the theoretical analysis to be of correctness.
