摘　　要：针对采用长短脉冲波形的雷达,存在用于补盲的脉间参差和实现多种功能的脉组参差两种发射时序。研究采用密集假目标样式对此类雷达进行干扰时,干扰信号时域跨周期造成干扰覆盖距离段与设置不匹配的问题并进行分析,提出单机时域多次触发及多机时域各自触发的干扰方法并进行仿真,验证了两种方法的可行性,方法能够为工程应用提供一定借鉴意义。For radars employing long and short pulse waveforms,there are two types of transmitting time sequences,namely pulse-to-pulse staggering for gap filling and pulse group staggering for multi-function.This study analyzes the issue of mismatch between the jamming range and the settings caused by the cross-period nature of the jamming signals in the time domain when dense false target jamming is employed to interfere with such radars.In this paper,two jamming methods featuring single-jammer multiple time-domain triggering and multi-jammer individual time-domain triggering respectively are proposed.In addition,simulation tests are conducted,which verifies the feasibility of both methods.This paper provides a reference for similar engineering applications.
