摘　　要：拖引干扰被广泛应用于对抗反舰雷达导引头,本文中对欺骗式拖引干扰的产生机理进行了分析,并结合反舰雷达导引头末制导跟踪流程,设计了基于波门递推的抗干扰算法,并通过干扰对抗试验验证了算法的有效性。Pull-off jamming is a widely used jamming technique against radar seekers on anti-ship missiles.In this paper,deceptive pull-off jamming mechanism is described at first,based on which an anti-jamming algorithm employing gate extrapolation is designed with the tracking process of a radar seeker in terminal guidance phase being taken into consideration.Anti-jamming test results show the effectiveness of the proposed algorithm.

关 键 词：雷达导引头 拖引干扰 波门递推
