用小波变换提高地震资料的分辨率

Improving the Resolution of Seismic Data with Wavelet Transform

小波变换具有时 频域局域化好的特性。利用小波变换的优良性质提出了一种地震资料高分辨率处理方法。该方法首先对地震信号进行小波分解， 再对小波分尺度信号进行合理的频率补偿， 最后将频率补偿后的小波分尺度信号进行小波反变换， 得到高分辨率地震信号。理论模型试算和实际地震资料处理结果证明了该方法的正确性和有效性。

Wavelet transform is characterized by good time frequency domain localization A method of high resolution processing of seismic data is developed by utilizing good character of wavelet transform The method includes three steps: wavelet decomposition, reasonable frequency compensation for wavelet decomposition signals according to spectrum whitening method, and wavelet reconstruction with the compensated signals The results of calculation and process show that the method is correct and effective
