基于统计模型的末区风场对再入弹头落点精度的影响及修正

Accuracy Error and Correction of Reentry Ballistic Missile Based on Stat Wind Field Model

在分析风场对弹头再入精度影响的基础上,提出了通过修订装订诸元的方法实现对再入弹头风场的修正。运用实测风场数据,拟合建立了风场的修正模型,仿真验证了拟合风场和实测风场对弹头落点偏差影响的差异,证明拟合风场和实际风场是比较接近的。弹道仿真表明,风场对再入弹头的影响随着导弹射程、射向的变化有明显的影响,通过所建立模型的修正,可以有效地提高弹头再入落点精度。

On the base of analyzing the affection of wind field that used in the ballistic computation and the method by changing the parameter of missile to correct of warhead wind field was put forward. The actual wind field parameter got by measurement was used to build a wind field error correction model. The ballistic simulation computation shows that the correction pattern created can effectively improve the accuracy of the reentry warhead, and the model is correct.
