弹道导弹助推段动态RCS特征仿真

A Simulating Study of BM's Dynamic RCS Characteristics in Flight Boost Phase

根据弹道导弹在助推段的运动特性进行弹道仿真。采用准静态法结合矩量法仿真导弹在助推段的动态RCS,通过与导弹静态全角度单站RCS的计算结果对比得到每一采样时刻导弹姿态的变化,采用N点截图的方法获取动态RCS的均值方差联合分布提取弹道导弹在助推段的动态RCS特征,由此分析导弹在助推段的轨道特性,作为助推段导弹目标识别的依据。

RCS of ballistic missile in the boost phase is the key information to missile early warning.In this paper,the trajectory simulation in the boost phase is built up based on the missile dynamic characteristics.A quasi-static method in conjunction with the method of moment is adopted to calculate dynamic RCS of missile in the boost phase.The missile attitude variations are obtained compared with the static RCS results of all incident angles.Finally,the original data is processed by using Npoint reduction method to get the joint distribution of mean value and variance of dynamic RCS,through which the trajectory characteristics are shown.
