说明：  广义S变换，具有良好的分析特性和局部的时频的特性，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，本文利用他们的他们的各自优点，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。  关键词：广义S变换，谱白化，高分辨处理(Generalized S transformation (GST) has good analyzing feature and good Time-frequency localization,. 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 seismic to get a high-resolution time signal. Theoretic modeling and field seismic data processing results has proved this method corrected and effective . )
