基于广义S变换的地震高分辨率分析

Study on High-Resolution Seismic Based on Generalized Stransform

Stockwell等人提出的S变换虽然与Fourier谱能保持直接联系,但是S变换中的基本小波不适用于地震资料处理,通过对S变换加以推广得到广义S变换。本文研究广义S变换在地震高分辨处理中的应用,并利用广义S变换进行地震高分辨率剖面处理。仿真实验和实际资料的处理对比结果均表明广义S变换在地震高分辨处理方面的可行性和有效性。

S transform （ST） is proposed by Stockwell et al. It is a the unique transform that provides frequency-dependent resolution while maintaining a direct relationship with the Fourier spectrum. This feature is very important for applications. However, the ST can＇t work well for seismic data analysis. So it is a necessary to develop or improve S transform, which are called generalized S transform （GST）.In this paper, generalized S transform is researched in the seismic high-resolution processing, and use generalized S transform to deal with high-resolution seismic profiles. Simulation experiments and real data processing results show that generalized S transform is feasibility and effectiveness in the seismic high-resolution processing.
