摘要
广义S变换,具有良好的分析特性和局部的时频特性,而谱白化和反褶积也是高分辨处理中的一种有效的频率补偿手段。文章利用他们的各自优点,使二者结合起来,该方法对地震信号用广义S变换分解,进行频率补偿再进行重构,得到高分辨率时间信号。理论模型试算和实际地震处理结果证明了该方法的正确性和有效性。
Generalized S transformation(GST)has good analyzing feature and good time-frequency localization,so the spectrum whitening and deconvolution is an effective tool for frequency compensation,Utilizing both their advantages,the method first conducts GST decomposition to seismic data,doing high frequency compensation and then reconstruction to get high-resolution time signal.Theoretic modeling and field seismic data processing results has proved this method correct and effective.
