光学制导巡航导弹实时航迹规划方法

针对光学制导巡航导弹的特点提出了一种实时航迹规划方法。建立了导引头受太阳逆光限制下的可飞航向角区域模型，结合可飞航向角与导弹的其他飞行约束条件对A*算法的搜索空间进行了规划。针对传统A*算法在规划前对所有地形进行平滑的低效规划方法，提出只对航迹每一步可行搜索方向上的地形进行实时平滑的A*算法，从而把对地形的平滑融入了每一步航迹的搜索过程。仿真结果表明，提出的航迹规划方法完全适用于光学制导巡航导弹，且在相同的条件下，实时平滑A*算法比传统A*算法的搜索效率更高。

Real-time path planning for optic-guided cruise missiles

According to the character of optic-guided cruise missiles,a real-time path planning scheme is presented.A model of permitted course area of missiles is established under contrary light conditions,and combining it with the other flight constraint conditions of cruise missiles,the search space of the A* algorithm is planned.Aiming at the inefficient planning way of smoothing all the digital terrain in the traditional A* algorithm,a new A* algorithm which only real-time smooths the possible path by each searc...
