The Allan variance and PSD were utilized to analyze the output of the FOG,and some main noise of the fiber optic gyroscope could be extracted and confirmed,then the performance of ARMA and AR of the FOG was evaluated.

• 利用A llan方差及PSD分析法对光纤陀螺输出信号的分析；有效地分离并确定影响光纤陀螺输出性能的几种主要随机误差源；并对所建立的光纤陀螺ARMA模型和AR模型的精度进行了评估.
