摘　　要：强电子干扰可压制被动导引头接收机,从而实现对抗反辐射武器的攻击以保护目标雷达的安全。为进一步分析电子干扰设备发射高重频脉冲对导引头宽带接收机的干扰效果,从评估指标脉冲截获数出发,首先分析了数字式宽带接收机和模拟宽带接收机的脉冲截获概率,然后分别对这两种接收机的脉冲截获概率进行仿真,进而算出脉冲截获数。结果表明高重频干扰脉冲实现了对宽带接收机的压制,降低了雷达信号发现概率,是对抗被动导引头的有效方法。Strong electronic interference can suppress the receivers of passive seeker to achieve interference with anti-radia⁃tion weapons to protect the radar.For further analyzing the jamming effect of high PRF pulses transmitted by electronic jamming equipment on the wideband receivers of seeker,starting from the evaluation index of pulse acquisition numbers,the pulse acquisi⁃tion probability of digital wideband receivers and analog wideband receivers is firstly analyzed.Secondly,the pulse acquisition prob⁃ability of these two types of receivers is simulated respectively,and then the pulse acquisition numbers are calculated.The results show that high PRF pulses can not only suppress the wideband receivers,but also reduce the detection probability of radar,which is an effective method against passive seekers.
