针对助推-滑翔无动力跳跃飞行器再入拉起后升阻比大小较为稳定的特点，设计了基于稳定升阻比的轨迹预测算法。首先对目标的弹道特性进行了分析，鉴于其再入后特有的跳跃拉升现象，将再入拉起时刻确定为轨迹预测算法的起始时刻；其次，根据防御方已知信息和未知信息对飞行器跳跃段运动方程进行了转化，给出了转化后运动方程中未知参量的计算方法，并设计了基于转化后运动方程的轨迹预测流程及算法；最后对算法进行了仿真验证，仿真结果表明所设计预测算法对助推-滑翔无动力跳跃飞行器再入拉起后的轨迹具有较好的预测能力。

A traj ectory forecasting algorithm of boost-glide unpropulsive skipping vehicle is designed based on the fixed character of the vehicle's lift-drag ratio.Firstly,by analyzing the track characteristics of this kind vehicle,the reentry-uprising time is determined as the beginning time of this algorithm because of the vehicle's unique reentry-uprising phenomena.Secondly,through integrating the known information with the unknown information to the defense system,the changed movement equation and algorithm of the un-known parameter are given.Based on the changed movement equation,the track forecasting flow and algo-rithm are designed.Finally,the simulation is done and the result shows that the forecasting algorithm has a better ability to forecast the latter traj ectory when the vehicle is uprising again.
