摘    要：小波分析引入了多尺度分析思想，可以对静态效应和深部异常，局部异常和区域异常，信号和噪声进行识别和分离。基于小波变换的特性，作者在频率域电磁测深静态效应的自动识别和压制、重磁异常分离的高精度方法、电阻率函数的奇性分析和深度反演、地震波速反演成像和噪声压制等方面成功地应用了小波分析理论。

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.
