一种基于“GM(1,1)”模型的火炮初速灰预测方法

A Kind of the Muzzle Velocity Grey Prediction Method Based on the GM(1,1) Model

火炮初速量测是火炮进行弹道准备中的一项重要内容,运用灰色理论探讨火炮初速预测问题,既有利于提高火炮射击精度的修正,又有利于进一步完善火炮初速测量雷达的使用操作和改进设计。针对火炮初速随机变化的特点,基于灰色理论中的GM(1,1)模型,构建火炮初速灰预测模型,确定预测结果精度检验方法。最后通过一应用实例验证了该方法具有一定的合理性与实用性。

The cannon muzzle velocity is one of the important contents in carrying on ballistic trajectory preparation. Managing the grey prediction to discuss the problem of the cannon muzzle velocity prediction, it is not only good to improve the correction of the cannon shooting prediction, but also is advantageous to perfect the operation and improvement design of the cannon muzzle velocity measure radar further. According to the random variable characteristics of the cannon muzzle velocity, this paper uses the GM（I,I） model in the grey theory, and then constructs the model of the cannon muzzle velocity grey prediction and makes sure the verifying method to the prediction result. Finally through an applying example, it verifies that this method has some rationality and practicability.
