To improve the prediction accuracy of the trajectory prediction methods, this paper studies the prediction methods. In this scheme, the impacts of earth rotation are overcome through the transformation of coordinates, the trajectory parameters of ballistic missile no-perturbance moving are taken as the initial value, the trajectory parameters are corrected by considering the influences of main perturbative force on the parameters, and establishes a prediction model of the entire passive trajectory by regarding the reentry phase as the extension of free phase. Simulation results show that this proposed method can improve the prediction accuracy of the trajectory.
