摘　　要：带有半主动雷达导引头的地空导弹武器系统攻击超低空目标,制导控制系统均会受到强烈的镜像干扰,导致脱靶量严重超差,不能满足设计指标要求.介绍了镜像干扰机理,并提出了抑制镜像干扰的新方法.仿真及飞行试验结果表明,用这种新方法对制导控制系统进行改进,能有效地抑制镜像干扰.The entire guidance and control system is jammed intensively by mirror-image jam when the surface-to-air missile weapon using semi-active radar seeker intercepts super low level targets, which results in serious missdistance deviations and doesn' t meet the requirements of design specification. The mirror-image jam mechanism is presented, and a new method to restrain mirror-image jam is proposed. The result of flight test and simulation shows that this method can be used to improve the guidance and control system and can effectively restrain mirror-image jam.
