由于无人机作战区域广阔,导致进行航迹规划时搜索空间巨大,通常的搜索算法需要较长的收敛时间和极大的内存空间。文章论述了无人机航迹规划时应考虑飞机最小转弯半径的约束,以及飞机的出发角度、目标点进入角度的要求,采用了Dijkstra算法进行航迹规划,仿真结果验证了该算法的有效性和实用性。 Because of the vast combat area of ​​UAV, resulting in a huge search space for track planning, the usual search algorithms require a long convergence time and a large memory space. In this paper, the constraints of the minimum turning radius of the aircraft, the departure angle of the aircraft and the angle of arrival of the target should be considered in the trajectory planning of the UAV. The Dijkstra algorithm is used to track planning. The simulation results verify the effectiveness of the algorithm And practicality.
