摘　　要：首先用小波分解的方法对陀螺误差的趋势项进行了分析 ,采用Allan方差分析的方法 ,对某型激光陀螺误差进行了建模及误差估计研究 ,将激光陀螺误差中的零偏、量化噪声、及随机游走噪声等误差成分分离出来 ,并对其统计特性进行了估计。In order to analyze the tendency of ring laser gyro (RLG) noise, a wavelets analysis method is presented. Using Allan variance method, the RLG’s errors estimating and modeling are studied in this paper. The bias, scale factor error and random walk error are separated from error source, and its statistic characteristic is estimated. The test results show that Markov noise is not basic ring laser gyro noise.
