中文摘要: 反舰导弹同时到达对于突破舰载近程防御武器系统具有关键作用,而撞击角度控制可提高杀伤效果。但现有方法存在一些不足。本项目研究大前置角情况下反舰导弹的撞击时间控制导引律和时间协同导引律,分别考虑无角度控制和带角度控制两种情况。针对大前置角情况下剩余时间估计误差较大的问题:提出一种大前置角情况下基于比例导引的剩余时间估计方法;通过构造一种新型带角度控制的比例导引律,提出一种大前置角情况下基于该导引律的剩余时间估计方法。为克服弹体动态特性及其不确定性的影响,保证目标不超出导引头视场,提出一种智能预测控制方法,无需线性化弹目相对运动方程,有利于提高导引性能。给出导弹未来时刻时变速度的预测公式,根据当前时刻导弹速度和加速度的实际测量值进行在线更新,解决实际导弹速度时变且具有一定不确定性情况下剩余时间的估算难题。通过仿真与实验进行验证。其成果可为我国研发具有同时攻击能力的先进导引系统提供理论与技术支撑。

英文摘要: Simultaneous arrival for anti-ship missiles plays a key role in breaking through close-in weapon system on warship, and impact-angle control can improve the destroying effect. But some drawback exists in the presented approaches. The project includes research on impact-time control guidance law and time-cooperative guidance law for anti-ship missiles in the case of large heading error, considering the following two cases, the case without impact-angle control, and the case with impact-angle control. Aiming at the larger error problem of estimating the time-to-go in the case of large heading error: present an approach of estimating the time-to-go based on propotional navigation guidance law in the case of large heading error; By constructing a new type of propotional navigation guidance law with impact-angle constraint, present an approach of estimating the time-to-go based on the proposed guidance law in the case of large heading error. Present an intelligent predictive control scheme that considers the dynamics of missile and its uncertainties, to keep the target within the Seeker's Field-Of-View, no linearization is required on the relative kinematics between the missile and target, which is propitious to improving the guidance performance. Present an approach to obtain formula for predicting the future veloci
