摘　　要：当雷达目标为复杂目标时,目标回波相位将受目标复杂的散射特性影响,传统的两点源相干干扰方法无法产生与目标回波相干的信号。针对该问题,基于目标的电磁散射特性,利用目标多散射点模型来调制接收到的雷达发射信号,以产生与目标回波具有相对稳定相位关系的干扰信号。为合理评估该技术的效果,根据单脉冲角跟踪雷达的典型应用场景,建立了单脉冲角跟踪末制导雷达作战模型,包括信号产生、处理模型及弹道模型,并搭建了闭环仿真平台;在该仿真平台上,进行了干扰效果验证实验,实验结果可为战术巡航导弹对抗研究提供有效和实际的参考依据。In coherent dual point-source jamming, it ＇ s not suitable to use a particle model for simulation of a target if the target ＇s scattering function is complex,so a coherent jamming method based on scattering function of complex target was developed. Jamming signals are ob tained from radar-transmitting signals modulated with the scattering function to be coherent with echoes. In view of evaluation of the jamming effect, the mono-pulsed angle tracking PD seeker is taken as an example to be analyzed in six degree-of-freedom trajectory simulation in the closed loop （PDRS）. The results of the verification tests could provide an effective and practical solution for parameters design and performance evaluation of tactical cruise missile.
