Gravity Anomaly Separation Using 2 - D Wavelet Approach and Average Depth Calculation

Abstract

In this paper, 2-D Multi-Resolution Analysis (MRA) is used to per? form Discrete-Parameter Wavelet Transform (DPWT) and applied to gravity anom? aly separation problem. The advantages of this method are that it introduces little dis? tortion to the shape of the original image and that it is not effected significantly by fac? tors such as the overlap power spectra of regional and residual fields. The pro? p o s ed method is tested using a synthetic example and satisfactory results have been found. Then average depth of the buried objects have been estimated by power spectrum analysis.
