Abstract:Wavelet analysis is a new tool for signal analysis, which has the property of the double localization in space-frequency domain and the focusing function. Based on the features of the wavelet analysis, wavelet analysis has large application value in geophysical prospecting which has special require for signal analysis tool. In this paper, the application results of wavelet analysis in geophysical prospecting were generalized. The practice proved that wavelet analysis has a rosy future in geophysical prospecting.
Key words: wavelet analysis geophysical prospecting signal analysis
