基于航路点搜索法的军用飞行器航路规划

摘要

为提高军用飞行器航路规划的效率和对威胁体的适应性，提出一种基于几何原理的、步进搜索的新航路规划方法：航路点搜索法。对禁飞区、雷达和防空武器、高山等地形障碍物进行建模，推导出航路规划时的代价函数。介绍在规划空间内如何选取航路点、使用航路点搜索法在获得的航路点中进行筛选，从而生成航路的过程和原则，并根据代价函数对规划出的航路进行寻优。通过算例对航路点搜索法进行仿真验证，结果表明，该方法简单有效，收敛性好，对威胁体的类型和数量不敏感，具有一定的工程应用价值。%A new method based on geometrical principle and stepping search, waypoint searching method, is proposed to improve the effectiveness and applicability with menace for route planning of military aircrafts. The models of flight-forbidden area, radars, air defense weapons and the terrain obstacles such as a high mountain are established, and the cost function during the route planning is deduced. The process and principle of how to obtain waypoints in planning space and how to select the waypoints which are acquired to make the route by waypoint searching method is introduced, and the optimal route is obtained with the cost function. The simulation based on waypoint searching method is implemented, and the results show that it is simple, has better convergence, and is not sensitive to menace. Thus, this method has a great value in the practical applications.
