摘要
For the problems exiting in real seismic data processing, such as S/N ratio and resolution, this paper utilizes 2D wavelet transform and multi-resolution analysis to attenuate noise and enhance resolution. Many calculations preseuted in this paper have shown that the data quality after multi-resolution analysising is improved.
