摘要
基于数据链的三维航迹规划算法研究对保障飞行器的任务完成和提高其自身的生存能力都很有意义。本文深入研究了A*算法的改进和应用问题,结合数据链通信的条件,改进基于A*算法的三维航迹规划算法。研究了数据链在航迹规划中的作用及通讯模型,并研究了在数据链通信情况下的基于A*算法的离线、在线、针对移动目标、可重选目标的航迹规划方法,并进行了软件仿真,验证了方案的有效性。
It is very important to study planning algorithm of flight trajectory based on data link. This paper studies the improvement of A ＊ algorithm and its application. In the condition of using data link to communication, an improved A ＊ algorithm as three dimension trajectory planning methods is presented. Furthermore, the model of data link communication is researched which to be carried out in a testing environment. Also in this environment, trajectory planning algorithm including off-line, on-line, using for moving objects or selected moving object, are proposed and then are tested by simulation.
