摘　　要：针对传统干扰方式无法有效干扰新体制雷达信号的问题,提出采用目前雷达主流干扰方式——间歇采样重复转发式干扰(Intermittent Sampling Repeat Forwarding Jamming,ISRJ),对连续相位调制—线性调频(Continuous Phase Modulation-Linear Frequency Modulation,CPM-LFM)信号进行干扰效果分析。建立了CPM-LFM雷达通信一体化信号模型。推导干扰信号的脉冲压缩表达式,分析了ISRJ脉冲压缩结果。从实际应用角度出发,与传统干扰方式对比说明ISRJ方式在一体化信号干扰上的优势。仿真结果表明,ISRJ能够有效干扰CPM-LFM一体化信号,影响雷达探测能力和通信性能,在干信比(Jamming Signal Ratio,JSR)为30 dB时,通信误码率为0.1938,实现中度干扰。To solve the problem that the traditional jamming methods can’t effectively jam the radar signal of new system,Intermittent Sampling Repeat Forwarding Jamming,the mainstream jamming method of radar,is proposed to analyze the jamming effect of Continuous Phase Modulation—Linear Frequency Modulation(CPM-LFM)signal.A CPM-LFM radar communication integrated signal model is established.The pulse compression expression of jamming signal is deduced,and the intermittent sampling repeat forwarding jamming pulse compression results are analyzed.From the perspective of practical application,as compared with the traditional jamming mode,the advantages of intermittent sampling repeat forwarding jamming mode in integrated signal jamming is described.The simulation results show that intermittent sampling repeat forwarding jamming can achieve effective jamming on CPM-LFM integrated signal and affect radar detection ability and communication performance.When the jamming signal ratio is 30 dB,the communication bit error rate is 0.1938,achieving moderate jamming.
