摘　　要：阐述了间歇采样转发干扰和间歇重复转发干扰的原理,基于线性调频脉冲压缩雷达针对间歇重复转发干扰进行了仿真,通过改变采样重复周期和采样脉冲占空比研究其对重复转发干扰效果的影响。研究了脉冲采样重复周期、占空比、干信比、恒虚警检测保护单元和参考单元长度之间的关系并进行了分析与验证。The principles of intermittent sampling forwarding jamming and intermittent repeated forwarding jamming were expounded.Based on chirp pulse compression radar,the intermittent repetitive forwarding jamming was simulated;the influence of sampling repetition period and pulse duty ratio on the interference effect on repeated forwarding jamming was studied.The relationship among pulse sampling repetition period,duty ratio,jamming-signal ratio,constant false alarm detection protection unit and reference unit length were analyzed and verified.
