| 摘 要： | 提出了一种飞行器在给定地形和威胁分布的威胁场进行低空突防的航迹优化算法。该方法首先对地形的高程栅格数据进行了图形简化预处理,将各种威胁叠加到地形图上,构成一个包含各种威胁的特定威胁场,再对其建立合理的有向图数学建模,用Dijkstra最短路算法进行航迹优化。航迹优化的过程中考虑了飞行器的过载限制,使优化航迹能够较好地满足飞行器各项性能指标及任务规划的要求,仿真结果显示,该算法简单快速,能很好地进行地形、威胁、障碍物的回避。

| Abstract: | This paper presents a new algorithm of trajectory optimization for aircraft in low altitude penetrating specified area.Simplifying the DTED from grid level to graphics level and the threat and obstacle are laid on the graphics to construct a specified region.After constructing a reasonable mathematics model,Dijkstra shortest route planning algorithm is given.The trajectory generated considering the over loading limitation of aircraft can meet the relative requisitions.The result of simulation stated this method is effective,and optimized trajectory can automatically avoid terrain,threat and obstacle. |
