Abstract：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.
