摘要:

本文提出了一种新的子波处理方法.该方法是在已知子波的基础上,利用子波自相关的零相位对称性,根括最小平方原理进行反褶积,最后得到零相位的压缩脉冲.经过上机试脸证明,该方法比原有子波处理方法有较大的改善.

关键词: 地震数据处理, 子波处理, 零相位对称

Abstract:

Wavelet processing is an important processing method in xiamic data proeessing. This paper proposes a new wavelet processing method,which is to use zero—phax symmetry of wavelet's auto—correlation based on a known wavelet,and to make deconvolution according to the least square method to obtain a zero—phase compressive pulx. Tested by rnmputer. the method proves to be much more improved than the original wavelet processing method.

Key words: seisthic data processing, wavelet processing, Zero-phase symmetry
