【Abstract】 The theory of Wavelet Analysis is introduced.The model of the signal in the fiber optic gyro(FOG)is given,then a drift elimination method based on Wavelet Analysis is presented.Multi-scale wavelet decomposition and Multi-resolution analysis(MRA)is done on the real time signal of FOG,and the feasibility of this method is verified.更多还原
