摘　　要：雷达波在传播时会产生遮挡与绕射现象,影响雷达对抗侦察接收机的检测概率,进而影响其截获能力.根据障碍物的不同拓扑结构,给出了单刃峰、圆顶峰、多重刃峰等不同地形因素对雷达对抗侦察接收机检测概率的影响分析,并在此基础上对不同的绕射情况下影响接收机检测能力的主要因素进行了仿真计算.仿真分析得到的结论在一定程度上可为雷达对抗侦察接收机作战部署提供准确的参考.The phenomenon of shelter and diffraction would occur while the radar wave propagating, whichaffects the detection probability of radar countermeasure reconnaissance receiver, thus hindering its capability ofinterception. This paper analyses the influences of various terrain factors on detection probability of radarcountermeasure reconnaissance receiver in terms of different topology structures of obstacles, including the singleedge peak, round top, multiple edge peaks and others, based on which, the main factors of affecting the detectioncapability of receiver are simulated and calculated in the case of various diffraction. The conclusions drawn fromsimulation analysis can be an accurate reference for the operational deployment of radar countermeasurereconnaissance receivers to some extent.
