Potential field methods are important geophysical methods used to study subsurface issues. In order to test various strategies for interpreting and analyzing field data of field potential, firstly artificial data obtained from artificial models is used. If the results are desirable, this solution will be used for the real data. By interpreting the potential field data, the characteristics of the source of the field, as well as depth and location, are determined. Most methods for interpretation of potential field data are performed in Fourier domain. The use of wavelet transform is a newer and more accurate solution for estimating of source parameters. This research examines the estimation of the depth and position of potential field sources by wavelet transform.
