摘　　要：线性调频脉冲压缩技术是当代高分辨率体制雷达的发展主流之一,因此如何对脉冲压缩体制雷达进行有效的干扰已经成为电子对抗领域的主要问题。从线性调频脉冲压缩体制雷达信号处理的基本原理出发,分析了间歇采样延时转发干扰对信号处理的影响,指出其不足之处,有针对性地提出了一种基于跨周期相位调制的相干干扰技术。通过仿真分析了其可行性和有效性,研究了参数的选取对干扰效果的影响。Linear frequency modulation pulse compression technology is one of contemporary high-resolution radar,so the effective jamming of the pulse compression radar has become the main problem in the field of electronic countermeasures. Starting from the basic principle of linear frequency modulation signal,the influence of intermittent sampling time-delay-jamming on signal processing is analyzed and its shortcomings are pointed out,finally a intermittent phase modulation jamming technology is proposed.The feasibility and validity of the method are analyzed by simulation,and the influence of parameter selection on the jamming effect is researched.
