摘要
确定安全走廊和参考轨迹是利用分层规划思想进行航迹规划时首先要解决的问题。综合考虑飞行任务、导航精度、飞行器性能、地形信息、敌方威胁位置和防空火力配置等因素,利用数字地图,用动态规划方法确定了飞行器的安全走廊和参考航线。针对导航系统精度和数字地图存在误差的情况,通过适当划分搜索空间网格保证了航迹的鲁棒性。最后利用模拟数字地形进行了仿真验证。
The safe corridor and reference should be firstly determined in hierarchical route planning. This paper gives a simple method to get them based on dynamic programming. The flight mission, the precision of navigation, the characteristic of aircraft, the terrain information, the hostile threat location, and the deploy of hostile air defense firepower etc are taken into account this method. In view of the situation that there are errors in navigation data and digital terrain data, the robustness of reference path is ensured according to choice the cell width of search space properly. A simulation using static terrain is made to test the method at last.
