摘 要: 小波分析引入了多尺度分析思想,可以對靜態(tài)效應(yīng)和深部異常,局部異常和區(qū)域異常,信號和噪聲進行識別和分離。基于小波變換的特性,作者在頻率域電磁測深靜態(tài)效應(yīng)的自動識別和壓制、重磁異常分離的高精度方法、電阻率函數(shù)的奇性分析和深度反演、地震波速反演成像和噪聲壓制等方面成功地應(yīng)用了小波分析理論。

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
