摘　　要：对多径效应下被动雷达导引头相位模型进行了理论推导,并通过仿真,分析了多种频率、速度、攻击角条件下被动雷达导引头测角受到的多径影响情况。仿真试验表明,大攻击角下多径影响较小。The phase model of passive radar seeker in multipath environment is deduced.The environment affect to angle of passive radar seeker is analyzed with different speed of anti radiation weapon,different attacking angle of anti radiation weapon and different frequency of radar.The simulation results prove that the environment affect to angle of passive radar seeker is smaller with large attacking angle of anti radiation weapon.

关 键 词：多径效应 被动雷达导引头 攻击角
