A 3-D vehicle path planning method for low altitude penetration based on an A~* algorithm in radar threat conditions is proposed.Digital terrain information is processed by an integrated terrain elevation smoothing algorithm at first,and a safe surface which integrates the maneuverability of UAV and mathematical models of radar threat are built,a terrain masking radar blind space is calculated.The A~* algorithm is used to plan three-dimensional vehicle paths on the safe surface which satisfies the terrain masking radar blind space finally.The simulation result indicates the method could obtain optimal path in a 3-D environment and the path planning algorithm is simple,efficient and easily realized in engineering.
