| 摘 要： | 介绍了一种飞行器低空突防三维航迹规划方法.通过分析敌防空区域地形方差,判断其地形特征,决定最佳离地高度,从而构建了飞行器安全飞行曲面.利用Dijkstra算法,在安全飞行曲面之上,进行二维航迹节点的搜索,达到三维航迹规划的目标.搜索空间维数的缩小,存储节点数目的删减,都加快了航迹生成的速度.威胁概率模型的建立,航迹代价函数的构造,权重比值的分配,使得规划出的航迹具有一定的威胁/地形回避和地形跟随效果.最后给出了算例和仿真结果.

| Abstract: | A 3-D flight-path generation method is introduced for air vehicle in low-altitude penetration.By analyzing variance of the terrain of enemy air-defense area and analyzing the characteristics of the terrain,the optimum safe altitude of the vehicle to ground is obtained,and the safe flight surface is constructed.Through planar node search on the safe flight surface using improved Dijkstra algorithm,the effect of the 3-D flight-path planning is achieved successfully.The search space dimension is reduced,the ne... |
