潜射弹道导弹定位定向误差传播模型

定位定向误差是影响潜射弹道导弹命中精度的重要因素。同时考虑几何项、初值项和引力项,得到了定位定向误差影响分析的完整解析解,并利用主动段状态空间摄动方程推导了定位定向误差的线性化传播模型。计算结果表明:所提方法计算速度快,速度偏差估计误差小于10%,位置偏差估计误差小于1%,可以满足精度分析的需要。

Positioning and Orientation Error Propagation Models for Submarine-Launched Ballistic Missile

Positioning and orientation deviations have prominent impact for hit accuracy of submarine-launched ballistic missile.In view of geometry item,initial state item and gravitation item,the paper put forward an integrated analytic solution about positioning and orientation deviation,and linear error propagation models are deduced.Experiment results show that the method has high calculating speed,and velocity deviation evaluation is less than 10%,and position deviation evaluation is less than 1%.So the method can satisfy requirement of missile accuracy analysis.
