为实现航空炸弹飞行中的风偏修正,提出了一种基于位置矢量合成关系的风场辨识方法。文中首先建立了制导炸弹系统仿真平台以及可用的简化风场模型,其次推导了具体的辨识步骤,从而仅根据飞行中的弹道偏差得到了实时的风场信息,为弹道风偏修正提供了可靠数据。最后通过数字仿真,验证了采用该方法进行飞行中的风场辨识是合理有效的。

A method of real-time wind identification in flight based on the relation of position vector was proposed to achieve the wind correction in flight of the aerial bomb. Firstly, a system simulation platform of guided bomb and the simplified wind field model were established, then the specific identification steps based on the wind field identification principles was derived, and the real-time wind field information was identified only from the trajectory deviations. Accordingly, a reliable wind data was provided for the wind correction in the trajectory. Finally, the method was proved reasonable and efficient by computer simulation results.
