一种基于雷达导引头的弹道导弹爆高解算方法

摘要

目前弹道导弹主要通过无线电引信测高来进行战斗部爆高控制，但弹头的再入环境对无线电引信测高装置的要求非常高，且引信存在着易被干扰的问题。为此，该文针对采用雷达景象匹配末制导的弹道导弹，提出一种基于雷达导引头的弹道导弹爆高控制方法，通过雷达导引头测高数据与惯性导航数据的融合处理，实时计算弹头飞行高程，来实现爆高控制，既保证了精度，又增强了抗干扰能力。仿真算例证明了该方法的有效性和爆高解算精度。%At present the height of the warhead of ballistic missile is measured by the radio fuze for the burst height control of the warhead, but the reentry environment of the warhead has very high requirement for the measure set of the radio fuze, and there exists the issue of the radio fuze to be jammed. In the paper, for the ballistic missile adopting the radar scene matching terminal guidance, a calculation method of burst height of ballistic missile based on radar seeker is put forward, by fusing the height measure data of the scene matching radar seeker and the inertial navigation data, the height of the warhead is calculated in real time to realize the burst height control, which ensures the precision and improves anti-jamming capability. The validity of the method and the calculation precision of the burst height are proved by simulation and calculation.
