Wavelet Analysis in the Signal Processing of FOG
Jiabin Chen · Fire Control and Command Control · 2005
The method that removes the noise in the Fiber of Gyro is studied.The feature of the noise in FOG is analyzed.On the basis of properties of 1/f~r noise in wavelet domain,it is using the wavelet de-noising method on the principle of Stein Unbiased Risk Estimate to select a threshold.It attempts to reject 1/f~r noise and white in FOG.The experimental result shows it is effective to suppress the noise of FOG and improve the SNR.
