In order to remove the noise from random drift signal of fiber optic gyroscope (FOG), the wavelet analysis technique is proposed in the filter Processing. Based on the component elements of random drift signal of FOG, mathematical model of random drift signal of FOG is built. According to the shortcoming of hard threshold and soft threshold, threshold function of forced denoising is used in signal filtering. It is shown from simulation and statistic analysis that the wavelet analysis technique
