提高导弹精度的重要途径是对惯性器件的各类误差予以分离,然后予以补偿,这就是所谓“误差分离”方法。实质上是一种间接测量。本文把误差分离的几种常用方法:简单最小二乘法(OLS),加权最小二乘法(WLS),最大似然估计法(ML),一般最大似然估计法(GML),一般最小二乘法(GLS),最大验后概率法(MAP),山脊回归法(RR),……等用统一的数学理论结合在一起,从而比较与评述他们应用的条件及物理意义。本文介绍了近年发展的一系列间接测量理论,可供需对参数进行间接测试的技术人员参考。
An important way to improve missile accuracy is to separate all kinds of errors in inertial devices and then compensate them. This is the so-called “error separation” method. In essence, it is an indirect measure. In this paper, several commonly used methods of error separation: OLS, WLS, ML, GML, GLS), maximum MAP (MAP), Ridge Regression (RR), ... and so on with a unified mathematical theory to compare and comment on their application of the conditions and physical meaning. This article introduces a series of indirect measurement theories developed in recent years, which can be used as a reference for technicians who need to indirectly test the parameters.
