An Autonomous Variable Step-length Trajectory Planning Algorithm for UAV
Shen Gongzhang · Journal of Projectiles.Rockets.Missiles and Guidance · 2008
Most existing trajectory planning algorithms for UAV adopt fixed step-length during searching.A fast autonomous variable step-length trajectory search algorithm for UAV was proposed since the threats are asymmetric and paroxysmal.The searching step-length is adjusted properly considering the location information of threats to reduce searching time.The simulation results show that with the algorithm,the trajectory that meets mission demands and restrictions quickly can be obtained quickly,which prove the correctness and validity of the algorithm.
