A route planning algorithm for unmanned air vehicle towards moving target
Zheng Chang · Journal of Astronautics · 2003
In contrast to the most existing route planners that are suitable for still targets,a new route planner for unmanned air vehicle towards moving target is proposed.Using the concept of Learning RealTime A search algorithm,and combining the flight of the vehicle with the process of route search,the novel algorithm can react to every move of the target.By searching the solutions in a larger area under limited time,the planner not only can meet the requirements of realtime inflight applications,but also can avoid infeasible areas effectively and enhance the performance of the resultant routes.It is shown from the experimental results that the routes are generated in realtime and are able to take into account various mission constraints.
