摘　　要：针对战术导弹在打击目标过程中导引雷达信号易被防空反导设备中雷达对抗情报侦察系统(ELINT)的瞬时测频接收机截获的问题,从瞬时测频接收机测量脉冲信号前沿的原理出发,在将脉内线性调频信号作为干扰信号与导引雷达信号满足时域部分重叠条件下,分析了干扰信号采用不同调制斜率时,对瞬时测频接收机测频结果以及分选结果造成的影响,最后通过计算机仿真验证了干扰效果。结果表明:采用脉内线性调频信号作为干扰信号,能够有效地对瞬时测频接收机造成干扰,进一步掩护战术导弹突防。Based on the fact that the tactical missile guidance radar＇ s signal is easily obtained by the in- stantaneous frequency measurement receiver in the ELINT system of the anti-air system. With the princi- ple of instantaneous frequency measurement receiver measuring the front of the pulse signal, the intra- pulse chirp signal as interference signals with guidance radar＇ s signal meet under the condition of tempo- ral overlap is studied, then the interference signal using different modulation slope is analyzed, jamming the instantaneous frequency measurement receiver＇ s frequency measuring and sorting , the influence of the jamming effectiveness is verified by computer simulation. The results show that the pulse in the linear frequency modulation signal as interfering signal, can effectively cause disturbance to the instantaneous frequency measurement receiver, covering tactical missile penetrating further.
