摘　　要：雷达导引头是主动寻式战术导弹的关键组成部分,它对目标进行探测,并引导导弹飞向目标,对导弹的作战性能有重大影响。主动雷达导引头大多采用脉冲多普勒单脉冲体制,因此研究该类型雷达导引头的建模和仿真有重要意义。经典的对雷达导引头的仿真主要是对制导控制系统的仿真,对信号的接收和处理则没有涉及。从各种干扰条件下主动雷达导引头的仿真与评估问题出发,采用相干视频信号仿真方法对脉冲多普勒雷达导引头进行了建模与动态仿真研究,并进行了仿真试验。最后给出了典型战情下的仿真结果,证实了该方法和模型的正确性。Radar seeker is a key part of the tactical guided missile of active homing type. It detects a target and guides a missile to fly at it, so its＇ performance affects missile＇ s efficiency greatly. Active radar seeker mostly adopts pulse Doppler monopulse radar system. So it is significant to research on the modeling and simulation of this kind of radar seeker. The classical simulation of radar seeker primarily model guidance control system without considering signal receiving and signal processing. Based on the simulation and evaluation problem of active radar target seeker in the condition of complicated ECM, modeling and dynamic simulation of pulsed Doppler radar seeker is studied. Then simulation is carried out and results verify its efficiency.
