Review of seismic P-and S-wavefields separation methods

ZG SUN, BL GU, YJ ZHANG, XY YAN, ZC LI - Progress in Geophysics, 2023 - en.dzkx.org
P/S wavefield separation is an essential step in the process of multi-component seismic data
processing. Separating P-and S-wavefields incompletely can obvious affect processing …

Polarization analysis and filtering of undersampled 3C seismic data in the frequency-slowness domain

IJ Sánchez-Galvis, W Agudelo, DO Trad, D Sierra - Geophysics, 2024 - library.seg.org
Polarization filters have emerged as a useful tool for coherent noise denoising in
multicomponent seismic data. By exploiting the polarization properties of seismic waves …
