火炮初速灰色预测建模与精度分析

火炮初速是受诸多因素制约的,可以利用灰预测对火炮初速进行预测.必须在测得4发以上的有效初速值后,才能利用灰色预测理论对数据进行建模分析,得到发射炮的火炮和装药批号初速偏差量,从而进行射击修正.应用GM(1,1)模型作数列灰预测,由于火炮初速是一个摆动量小的一维数组的预测,因此,火炮初速在建立了GM(1,1)模型后,必须以灰数列预测模型实施滚动检验对其精度进行必要的分析.

Grey Foresee Model Building and Precision Analysis of Muzzle Velocity

Muzzle velocity gets many factor restriction,which can be foreseen with grey forecast.After measuring no less then 4 effective values,we can use grey forecast theory to built model analysis for data,and get the projecting gun' s first fast deviation of cannon and gunpowder number for shoot correction.When applying the model of GM(1,1) to make series grey forecast,muzzle velocity is a one-dimension array forecast that swings amount is small,therefore,after establishing GM(1,1) model of muzzle velocity,we mus...
