无人作战飞机在线航路规划算法

针对无人作战飞机单机自主对地攻击过程中航路在线规划问题,在以栅袼形式表示的数字地图中,通过对威肋源建模、数据结构组织、估价函数建立、优化算法等多个方面进行改进,提出了一种基于A*算法的改进型规划模型.在保证规划有效性的同时,减小了搜索空间,进而提高了规划算法的实时性.仿真结果表明,该模型能够有效减弱规划结果对于栅格数字地图精度的依赖程度,为进一步开展在线规划及无人作战飞机实时路径重规划研究提供了券者.

On-Line Path Planning Algorithm for UCAVs

On-line path planning capability is very important for a single Uninhabited Combat Aerial Vehicle(UCAV) in carrying out autonomous ground attack missions.In grid-format digital map,through improvements to threat modeling,data-structure organization,cost-estimate function and optimum algorithm,an improved path planning model is put forward based on A* algorithm.The algorithm can reduce the search space and thus improve the real-time performance while guarantee the effectiveness of the path planning.Simulatio...
