航迹规划的目的是要利用地形和敌情等信息,规划出生存概率最大的无人飞行器突防轨迹。通过对航迹规划任务的仿真需求分析,对无人飞行器的航迹规划进行了研究。首先根据遍布威胁的战场环境,构造了基于威胁源的Voronoi图,得到规避威胁的航迹路线;然后采用Dijkstra算法,搜索出最优航迹路线;最后利用Visual Studio.Net 2010开发平台,在MS SQL Server 2008数据库支持下,运用Visual C#2008编制图形化界面,设计开发了无人飞行器航迹规划仿真系统,并给出了开发结果,实现了仿真结果的图形显示,为进一步的研究航迹规划奠定了基础。
The purpose of track planning is to use the information such as terrain and enemy conditions to plan the trajectory of the unmanned air vehicle that has the highest probability of survival. Through the analysis of the trajectory planning task simulation needs, the trajectory planning of UAV is studied. At first, based on the battlefield environments where threats exist, a Voronoi diagram based on threat sources is constructed to get the flight path to avoid the threat. Then the Dijkstra algorithm is used to search the optimal flight path. Finally, using Visual Studio.Net 2010 development platform, With the support of SQL Server 2008 database, a graphical interface of Visual C # 2008 is designed and developed. The UAV flight path planning and simulation system is designed and developed. The development results are given and the graphical display of the simulation results is achieved. Planning laid the foundation.
