Abstract:

Path planning plays a significant role on the unmanned aerial vehicle (UAV) mission planning. It is aiming at finding a safest UAV trajectory of optimal flying cost, considering the battlefield environment and other mission requirements. Based on the parallel ability of ant colony optimization (ACO) algorithm, a multi-precision planning window method is proposed. Based on the initial trajectory, it can automatically set multiple local planning windows with specifical planning precisions and optimization parameters, and then parallel path modification in a short time. Simulation analysis shows that the algorithm parameters configuration and planning accuracy are different in different battlefield environments. Through the optimization and adjustment of multi-precision planning window, the final flight path can adapt to different battlefield environment, and has better planning efficiency and accuracy.

Key words: unmanned aerial vehicle (UAV), path planning, ant colony optimization (ACO) algorithm, multi-precision optimization, optimization algorithm
