摘要
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。
The wavelet transform is a new branch of mathematics, which has been widely used in seismic exploration. In the paper, we use the wavelet transform to perform the potential field data processing, andderive 2-D wavelet transform formula form 1-D wavelet transform formla. A good processing result forthe model data and practical data has been achieved. It proves that 2-D wavelet transform can play animportant role in extracting areal regional anomaly and local anomaly and removing high-fraquency weakmagnetic interference.
