| 摘 要： | 随机漂移是影响光纤陀螺精度的重要因素。根据光纤陀螺静态漂移测试信号,利用Allan方差法对光纤陀螺随机漂移误差进行了分离和辨识,并分析了系数拟合过程中最小二乘法的病态矩阵问题。最后探讨了利用AIC准则和长自回归法建立光纤陀螺随机漂移ARMA模型的方法,为进一步对光纤陀螺输出信号进行滤波处理奠定了基础。

| Abstract: | Random drift is a important factor impacting the precision of FOG.Using the test data of FOG,the components of FOG random drift were separated and distinguished by Allan variance,and the ill-conditioned matrix in least squares fit of coefficients was analyzed.Finally,modeling method of ARMA of FOG random drift based on AIC criteria and long autoregression was discussed,building the foundation of filtering the output signal of FOG. |
