摘要
The unmanned aerial vehicle (UAV) path planning algorithm based on the rapidly-exploring random tree (RRT) can only quickly get a feasible path, but cannot obtain a near shortest path. To solve the path optimization problem, a mixed population RRT algorithm is proposed on the basis of the environmental potential field based RRT. The algorithm optimizes the path section to shorten the initial path with self-optimizing colony and synergy-optimizing colony. Meanwhile, the self-optimizing colony will search globally on the mission space, which makes the algorithm obtain a global optimal path. Afterward the B-spline is used to smooth the path node for a trackable path that meets the UAV dynamic constraints. Simulation results demonstrate that the proposed method can get a near optimal path with the fast convergence rate considering radar thread and the length of path, and the convergence efficiency is satisfactory in different mission environments. © 2020, Editorial Office of Systems Engineering and Electronics.
