Application of Real-Time Wavelet Threshold Filtering in FOG Attitude Measurement System

摘要：

　　A wavelet method is introduced to compensate stochastic errors of FOG attitude measurement system,analysing and comparing threshold and threshold function principle,a new threshold function combining with soft and hard threshold was designed.Adopting data moving window realizes recursive computation and real-time data update and solves filtering signals boundary problem with symmetric periodic extension method,and achieves real-time wavelet threshold filter.Experimental results show the feasibility of the real time wavelet threshold method in FOG signal de-noising,the real-time wavelet de-noising algorithm with new threshold function has the advantages of single algorithm.which improves the precision and stability of the FOG.
