摘要 本文在计算和分析光纤陀螺信号自相关函数的基础上,采用小波变换分析了光纤陀螺的噪音叠加模型,指出中高精度光纤陀螺的主要噪音成份为分形布朗运动(FBM).分析其噪音源并对系统进行改进. Based on the calculation and analysis of the auto-correlation function of the noise in fiber optic gyros (FOG), the noise model which is addition of Gaussian white noise (GWN) and fractal Brownian motion (FBM) is analyzed by an algorithm of orthonormal wavelet transform. An important conclusion is presented that the FBM dominates the noise in high performance fiber optic gyros. The noise sources are analyzed and the fiber gyros system is developed.
