交叉眼干扰在反舰导弹突防中的应用

Application of Cross-eye Jamming in the Penetration of Anti-ship Missile

针对反舰导弹突防中面临的单脉冲雷达威胁,提出了一种弹载自卫式单脉冲雷达干扰技术。交叉眼干扰技术利用波前扭曲引起了跟踪雷达的瞄准点向更强干扰信号方向的位移。选择合适的干扰信号参数可以使被干扰雷达形成最大测向误差或疑似多路径误差。文中探讨交叉眼干扰的一种途径,并给出了被干扰雷达角误差的分析和计算机仿真结果。

In view of the mono-pulse radar menace in the penetration of anti-ship missile, the missile-borne self-screen jamming technique of mono-pulse radar is proposed. Cross-eye jamming technique causes a displacement of the tracking radar aiming point in the direction of the stronger jamming signal by means of wave-front distortion. Choosing the appropriate parameter of the jamming signal can make the jammed radar form the biggest direction error or like multi-path error. This paper discusses a way to realize the cross-eye jamming, presents the angle error analy- sis and computer simulation results of the jammed radar.
