摘　　要：脉冲压缩雷达作为一种抗干扰能力很强的新型雷达受到了广泛的关注,如何对其进行有效干扰是一项亟需解决的课题。在对线性调频脉冲压缩雷达信号分析的基础上,研究了噪声干扰、脉冲干扰、频移干扰、延时干扰对该雷达信号的干扰效果,通过计算输入、输出信干比比较了不同干扰的干扰效果。通过仿真,给出了最佳的干扰信号样式。Pulse - compression radar, as a strong anti -jamming capability of new radar has been widespread concerned, and how effective interference is an urgent need to address the issue. Based on analysis of LFM Pulse- compression radar signal, study on the effect of noise jamming, pulse jamming, shift - frequency jamming and time - delay jamming to jam the LFM pulse-compression radar signal. By calculating the SNR of input and output,comparing the different effects of jamming. By simulation,the best jamming signal is proposed.
