弹道导弹预警仿真系统中弹道构造方法

建立符合作战想定要求的弹道导弹飞行轨迹模型,并按仿真时间步长推算弹道导弹的位置状态,是构建弹道导弹预警探测仿真系统的首要任务。首先在不考虑地球自转的情况下,按照指定的发射点和落点,依据最小能量弹道理论建立了弹道导弹关机点参数计算模型和被动段运动学模型。在此基础上,采用迭代的方法计算考虑地球自转时的弹道导弹关机点参数,并在地心惯性直角坐标系下构造了弹道导弹的被动段弹道。最后将利用法构造的弹道参数与STK中对应参数进行了对比分析,结果证明了所提出方法的正确性。

Study on Construction of Trajectory for Ballistic Missile Early Warning Simulation System

Building ballistic trajectory and calculating ballistic missile’s position are pre-requisite for constructing ballistic missile early warning simulation system.Firstly,based on minimal energy trajectory theory,this paper built missile closing engine point mathematic model and passive phase kinematic model under the hypothesis that the earth did not rotate.Secondly,the accurate missile closing engine point uneler the considering of earth rotation was calculated and the ballistic missile passive phase trajectory under the inertia rectangular coordinate systems was build.Lastly,the ballistic para meters using this method were verified by the parameters using STK,the results demonstrate the correctness of this method.
