基于威胁联网环境的一种无人机航迹重规划方法

威胁联网环境中,无人机需要对运动威胁进行规避以安全到达终点。通过建立无人机和威胁的运动模型,并对每一时刻无人机和运动威胁的相对位置进行实时分析;提出了一种基于可飞性分析的航迹重规划方法;最后对该方法进行仿真实验。仿真结果表明,该方法增强了无人机对运动威胁的规避能力。

A Path Replanning's Method for UAV Based on Threat Netting

In the environment of threat netting,UAV is required to avoid the moving threats to reach terminal safely. The precise motion model of UAV and moving threats is established in this paper,and the relative position of UAV and moving threats is analysed. Then a path replannng's method based on analysis of safe flight is proposed. The simulation experiment of this method is carried out finally. The simulation results show that this method improved UAV's ability of avoid moving threats.
