摘　　要：弹道导弹的跟踪是弹道导弹防御系统中最核心的问题,建模弹道导弹运动模型是仿真弹道导弹的飞行轨迹和研究弹道目标跟踪的前提和基础。对包含多级助推段弹道导弹的运动模型进行建模,并详细分析了弹道目标的加速度受推进力、空气阻力、地心引力和外在力的影响;进一步描述了弹道导弹轨迹仿真的流程。通过仿真实验得到含三级助推器弹道导弹的飞行轨迹,并分析了多级助推段对速度和加速度变化的影响。这对于研究中远程弹道导弹跟踪问题是非常有意义的。Tracking ballistic target is the most core problem in missile defense system.The ballistic model is the prerequisite of the simulation of ballistic missile trajectory and the research of ballistic object tracking.The paper addresses a mathematical model describing the motion of ballistic target which contains multiple-stage boosters.The total acceleration acting on the ballistic target has been decomposed into four terms：thrust,atmospheric drag,centrifugal force,and apparent forces.Further,a simulation flow of ballistic missile trajectory is described.From simulations,a flight trajectory of ballistic missile with three-stage boosters is obtained.The variations of the speed and acceleration of the ballistic target are analyzed.The effort has important significance for the research of tracking medium-range and long-range ballistic missiles.
