随机风对弹道落点散布的影响

Influence on the Trajectory Placement Dispersion of Warhead due to Stochastic Wind

弹道上风的变化及对射程侧偏的影响比较复杂，关键是空气的流动受季节、昼夜、地形、海陆、高度、纬度等多种因素影响，具有一定的随机性。因此，本文就随机风对弹道偏差的影响进行理论分析。首先建立随机风的风场模型，然后针对建立的模型进行弹道仿真分析，为弹道设计提供理论上的分析。

It is a complicated issue that the wind has effect on the range and its lateral range of the warhead. The air flow has been affected by season, day and night, terrain, height and latitude, which have some randomness. Theoretic analysis has been carried out on the trajectory dispersion of stochastic wind. The model of stochastic wind has been founded, and the ballistic trajectory simulation had been performed based on the model. This provides some theoretic reference for trajectory design.
