基于Allan方差的陀螺随机误差分析

随机误差是陀螺误差分析中重要的一部分,将Allan方差用于陀螺随机误差分析中,首先介绍了Allan方差的计算步骤,其次详细论述了随机误差的类型及其在Allan方差双对数图中的表现形式,最后通过仿真以及实测数据进行验证,结果表明Allan方差可以对各种误差源的统计特性进行辨识,是一种简单实用的陀螺随机误差识别方法。

Stochastic Errors Analysis of Gyro Based on Allan Variance

Stochastic errors are important part of the gyro errors , Allan Variance was used to analyze the gyro stochastic errors .The computation process of Allan Variance was firstly introduced , and then the types of stochastic errors and their performances in Allan Variance figures were discussed particularly , the simulated data and real data were used to validate the viewpoints , and the test results showed that Allan Variance could distinguish the statistical characteristics of different errors , and it was an simple and practical way to distinguish stochastic errors of gyro .
