| Abstract: | The development and application of fiber optic gyro(FOG) are introduced. The theory of wavelet analysis and the fast algorithm of wavelet transform are introduced. The model of the fiber optic gyro drift and the meaning of zero drift are clarified, principle of some methods for eliminating signal zero drift is analyzed. A drift elimination method based on wavelet analysis is presented. Multi-scale wavelet decomposition and multi-resolution analysis (MRA) are used in the real time signal of FOG, and the validity of wavelet filtering is verified. |
