USE OF ALLAN VARIANCE FOR PRACTICAL ASSESSMENT OF NOISE STRUCTURE OF SINS SENSING ELEMENTS

摘要

The paper deals with five types of noise components of the Allan variance method examined by a simple model of a measuring channel. These noise components are given in explicit manner by a combination of independent Gaussian random values (the white noise). The paper describes the relations between the model parameters and the coefficients of the polynomial approximant of the Allan variance curve. The restrictions are imposed on the measurement correlation, greatly separated in time. Their impact on the shape of the Allan variance curve is analysed, and the corresponding constraint equations are given.
