1) spectrum whitening
谱白化
1.
Improving resolution of seismic data using wavelet spectrum whitening.;
小波谱白化方法提高地震资料的分辨率
2.
The spectrum whitening based on Fourier transform and the frequency increaseof orthogonal wavelets can be used to raise the resolution of seismic data;however,they divide frequency roughly,so that signal energy varies greatly in different frequency bands, often causing the "noodles phenomenon"of signals in time domain.
采用傅氏变换的谱白化方法及正交小波的增频措施可以提高地震记录的分辨率。
3.
In allusion to field data acquisition parameters affect the resolution,analyzed some important module principles such as statics,deconvolution,velocity analysis,Q-compensation and spectrum whitening etc.
针对野外数据采集参数对分辨率的影响,对资料处理过程中静校正、反褶积、速度分析、Q补偿及谱白化等几个重要模块原理进行分析,指出在高速岩层中数据采集,应采用小药量激发,小道距,小排列,全三维,不组合、单点数字检波器接收。
2) spectrum sharing whiten
分频谱白化
1.
This paper introduces a spectrum sharing noise elimination method of stacked seismic data, which can stack time domain trace with spectrum sharing whiten and consistent correction stack, which can eliminate the residual effect and noise by trace of surface explosion, receiving different, inclined angle and surface so on, and thus improves the resolution and signaltonoise ratio of seismic data.
该方法可对叠后各时间场道集记录进行分频谱白化与一致性校正迭加,消除由于地表激发,接收不一致,倾角及表层因素引起的剩余时差和噪音对记录的影响,从而提高地震记录的信噪比和分辨率。
3) poststack spectrum whitening
叠后谱白化
4) time varied spectrum whiten
时变谱白化
5) time-space variant spectrum whitening
时空变谱白化
1.
In view of the limitation of"time-variant spectrum whitening"software that is used in some data processing centers,we then recommend here time-space variant spectrum whitening method.
针对目前一些计算中心应用的所谓“时变谱白化”软件的局限性，本文提出了一种时空变谱白化的处理方法，即在纵向上分时窗提供不同的滤波器频带，横向上再用控制点控制滤波器的横向变化。
