UAV Route Planning Research Analysis

首先介绍无人机航迹规划的研究方法,基于无人机的飞行性能特性、可能遇到的敌方威胁及高精度数字地图等相结合建立模拟地形的等高线图。根据无人机的任务分配、任务载荷要求、航迹规划过程中可能遇到的高度约束、转弯角约束、时间约束、威胁约束、爬升角约束、最小步长约束等各种约束,选择时间代价、性能代价最优的目标函数,采用A*算法对无人机从起始点到目标点的航线进行综合规划,得到全局范围内最优的参考飞行航线。仿真结果表明该方法能够满足无人机航迹规划的任务要求。

The UAV route planning research method was firstly introduced.Based on the UAV flight performance characteristics, the enemy threat and high precision digital maps, the terrain contour simulation maps were established.According to the requirements of the UAV task allocation, task load, the height constraints, the time constraints, the threats constraints, the climbing angle constraints, the minimum step length, Choosed the time and performance cost objective function, based on the A＊ algorithm, the global optimal flight path from the starting point to the target point.The simulation results shown that the method could satisfy the UAV route planning requirement.
