| Abstract: | 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. |
