多尺度分解在地震信号处理中的应用

Application of Wavelet on Seismic Signal Processing

利用小波分析中的多尺度分解及信号消噪技术 ,对记录不清、信噪比小、震相无法辨认的地震信号进行处理。结果表明 :多尺度分解在弱震信号提取和弱震相的识别等方面有很好的效果。

Making use of muti-scale decomposition and signal noise-removing technique,the authors processed bad-recording,low signal-to-noise signal,which with unclear seismic phase.The result shows that wavelet analysis has good effects on drawing out weak seismic signal and picking its phases,but also has influence on magnitude value.
