小波变换是近年来发展起来的新的数学分支，在地震勘探中已广泛应用。本文引入小波变换进行位场数据处理，由一维小波变换公式推导了二维小波变换公式，并对模型实验数据和实测数据进行了分解处理，取得了较好的结果。证明二维小波变换对于提取面积性的区域异常、局部异常及消除高频弱磁干扰具有重要意义。
Wavelet transform is a new branch of mathematics developed in recent years and has been widely used in seismic exploration. In this paper, the wavelet transform is introduced to carry out the data processing of the field. The formula of two-dimensional wavelet transform is derived from the one-dimensional wavelet transform formula. The experiment data and the measured data are decomposed and the good results are obtained. It is proved that two-dimensional wavelet transform is of great significance for extracting regional anomalies, local anomalies and eliminating high frequency weak magnetic interference.
