Study progress of wavelet transform applying in length-of-day change
Dechun Liao · Progress in geophysics · 2007
With the advance in space geodetic techniques,observations about length-of-day(LOD) change reach unprecedented precision and resolution.We need to use the appropriate mathematical methods to analyze these observations and extract valuable information from observed series.In recent years,the wavelet transform is applied to data processing in astronomy and Earth science fields.Through expansion,contraction and translation arithmetic,it can carry on thin analysis with some scales to some time series,and withdraws the effective information.This article reviews study progress about wavelet analysis in LOD change.Intending research aspect is discussed in the end of this paper.
