低空突防航迹优化就是综合考虑飞行器的各种约束,为飞行器规划出一条从起始点到目标点之间满足作战要求的路径,以保证安全完成突防任务。文中针对一般A*算法航迹规划算法速度慢,无法满足实际飞行要求的问题提出了基于概略图的航迹优化算法,将数字地图提炼成立体连通概略图,在这个立体连通概略图上再运用A*算法进行航迹优化。仿真结果显示,该算法大大缩短了航迹规划的时间,为算法的实际应用打下了坚实的基础。

The route optimization of low altitude penetration is a comprehensive consideration of various constraints of the aircraft, and a path is designed for the aircraft to meet the operational requirements from the starting point to the target point, so as to ensure the safe completion of the penetration mission. Aiming at the problem that the general A algorithm is slow in trajectory planning and cannot meet the actual flight requirements, this paper proposes a trajectory optimization algorithm based on sketch map. The digital map is refined into a volume-connected skeleton diagram, and then the A algorithm is used to optimize the trajectory on this stereo-connected skeleton diagram. The simulation results show that the algorithm greatly shortens the time of route planning and lays a solid foundation for the practical application of the algorithm.
