摘要
本文利用状态空间法在三维随机风场中对地面风的影响进行误差分析,导出误差的数学模型,并在数值结果的基础上提出了实用的修正模式,包括火箭主动段弹道风的简便换算方法,换算系数的确定,最有利的测风高度,测风次数,各次测风的时间间隔等,这个模式对现有的野战火箭炮兵都是可用的。
In this paper, the error for the effects of the ground wind in a three-dimensional random wind field is analysed by applying the state space method, the mathematical model of error is derived and a practical compensation model based on the numerical result is provided. It consisits of the simplified coverting method for ballistic wind in the active phase of the rocket, determination of the conversion coeffieiend and the most optimum altitude and times for wind measurement, and the time interval between the measurements. This model is useful for all the rocket artillery units.
