Yu Lei · Systems engineering and electronics · 2008
The common methods in the path planning for aircraft one optimizing the path inflying surface based on the smoothed digitol terrain,but these methods add the restrained conditions of the digitol terrain.A path planning scheme for aircraft based on improved A* algorithm is presented,which looks quite promising for the path planning problem.The cost function on the base of real terrain threats and fire threats is pnesented,the improved A* algorithm is given,to combine search optimum path and the smooth digital terrain.Finally simulation examples are given.The simulation results show that the improved A* algorithm proposed can get the satisfactory path in 24 seconds.It indicates that the proposed algorithm has better capability compared with traditional A* algorithm,which can satisfy path planning for aircraft.
