攻坚型图像制导导弹水平攻击坚固工事时,落角越小越有利于随进战斗部成功随进。根据简单的导弹运动模型,利用拉格朗日方法推导了一种同时带有落点和落角约束的弹道成形水平攻坚的最优制导律,给出了制导系统的弹道纵坐标、过载、弹道倾角随制导时间的变化关系,以及不同的末制导时间对制导规律的影响,为型号研制提供了理论依据。

When the image guided missile attacks on the surface of strong fortification horizontally, the smaller the impact angle is, the easier for the follow-on warhead to successfully follow. According to a simplified motion model of missile, the Lagrangian was adopted for deducing an optimal trajectory shaping horizontal attack guidance law with falling point and impact angle constraint. The vertical trajectory coordinate, inclination and overload controlled by guidance system and functions of guidance time, as well as the influence of remainder guidance time were studied. The research provides the theory reference for product development.
