风切变对弹道落点散布的影响

Effect of Shearing Wind on the Trajectory Dispersion

弹道上风的分布不均匀随着高度变化而变化，因而存在风切变。不同的风切变对射程产生不同的影响，风切变分为垂直切变和水平切变，而水平切变比垂直切变小得多。因此，本文就垂直风切变对弹道偏差的影响进行理论分析，首先建立风切变的风场模型，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 asymmetry for the ballistic wind that changes with the altitude, which exists the shearing wind, different shearing wind has different effect on the range. The shearing wind has vertical and horizontal wind, while the effect of horizontal shearing wind on the range is smaller than that of the vertical shearing wind. Theoretic analysis has been carried out on the trajectory dispersion of the vertical wind. The wind models of vertical shearing wind have been founded, and the ballistic simulation had been performed based on the models. This provides some theoretic reference for trajectory design.
