摘要
作者在本文考虑到地震道信号的分形特征,选取了具有紧支集的样条小波对信号作小波变换,相应地提出了利用小波变换的极大模值来检测地震道奇异性的方法。并用了应用实例来说明。
Considering the fractal property of seismic trace in this paper, a compactly supported spline-wavelet is selected for the seismic trace's wavelet transform. A method to detect the singularity of seismic trace is presented by wavelet transform maxima. An example shows that the method for dealing with the seismic data is very efficient.
