| Abstract: | Taking aim the limitation of traditional A-Star algorithm in route planning for unmanned aerial vehicles( UAVs), an improved A-Star algorithm that com Dines with aircraft kinematics equation was presented to solve the UAVs，threat avoidance in unknown environment. A route planning’s method was studied at the condition of considering comprehensively influence factors of route cost. A numerical simulation in reference route planning for UAVs demonstrates the efficacy of the improved algorithm. |
