摘　　要：水下超空泡航行器面向作战目标的直航弹道特性,在目标的机动规避和主动防御下,攻击策略将在一定程度上受限。针对该问题,设计了应对不同作战环境的机动攻击弹道和规避攻击弹道;建立了机动弹道水平运动模型,分析了机动弹道控制变量及主要影响因素;最后在给定的约束条件下,对预设弹道进行仿真。仿真结果表明航行器姿态变化平稳、弹道规划合理。In view of inherent property about rectilinear motion trajectory of supercavitating vehicles,two anticipant trajectories are programmed in order to respond the operational environment of maneuver evading and proactive protection.A motion model of underwater vehicle in horizontal plane is built considering the research of supercavitating maneuver trajectory,the control system is preliminarily analyzed and studied,and the state variable having an effect on maneuver trajectory is defined.At the end of the paper,the anticipant trajectory is simulated,such as the quality factor and the area.The results indicates that the variation posture of vehicles is steady and programming of trajectory is proper and appropriate.
