为了实现打击效果最优化,制导方法不仅要能获得最小的脱靶量而且要能够按照一定的期望攻击角度对目标实施打击。针对末端攻击角度约束这种特殊作战要求,详细推导弹目相对运动方程,得到了攻击角度与弹目相对运动状态相关的运动模型。基于Lyapunov方法设计了一类能够实现在全局范围内对期望攻击角度跟踪的制导方法,推导出了相应的制导律。通过数学仿真验证了该制导方法的正确性与可行性。
In order to optimize the combat effectiveness, the guidance method should not only obtain the minimum miss distance but also be able to attack the target according to a certain desired attack angle. According to the requirements of special attack such as restraint of terminal attack angle, the relative equations of motion of projectile are deduced in detail, and the motion model of attacking angle relative to the relative motion of projectile is obtained. Based on the Lyapunov method, a kind of guidance method that can track the desired attack angle in the global scope is designed and the corresponding guidance law is deduced. The correctness and feasibility of this guidance method are verified by mathematical simulation.
