摘　　要：为了提高弹道预测方法的预测精度,研究了弹道预测方法.通过坐标变换克服地球自转的影响,将弹道导弹无摄运动的轨道参数作为初值,考虑主要摄动力对轨道参数的影响,对轨道参数进行修正;并将再入段看成自由段的延伸,建立了整个被动段弹道预测模型.仿真结果表明,该方法提高了弹道预测精度.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.
