Trend Extraction of Gyro's Drift Based on Wavelet Analysis
Zhe Charles Zhou · Journal of Chinese Inertial Technology · 1999
Based on multiscale analysis,a series could be divided into a smooth trend and a local detail by using Debechies's orthonormal wavelet basis.An algortim of signal eature extraction is presented based on Multiscale theory in this paper.The simulation results indicate that this approach is feasible in effecticely estimating the sigmal's trend.At last,this approach is applied to model the gyro's drift,and the trend of a gyro's drift extracted successfully.
