For unmanned combat aerial vehicle (UCAV), the strike trajectory must be calculated quickly after the target is determined in order to ensure the timeliness of the attack process. Aiming at the requirement of three-dimensional trajectories at the end of attack mission, a path planning method for UCAV in terminal of target strike is proposed in this paper. In the first part, the research background and the urgent requirements are analyzed. Then, four assumptions based on the features in terminal of target strike are proposed to simplify and model the problem. In the third part, the method of path planning with two tangent circles is presented in detail. The discussion of the feasibility and optimality in the projection plane, and path adjustment in three-dimensional space considering the kinematic constraints, are presented subsequently. Finally, simulation results under various conditions are given, to verify the performance of the proposed method.
