Seismic diffraction separation in the near surface: Detection of high-contrast voids in unconsolidated soils
P Bakhtiari Rad, CJ Hickey - Geophysics, 2021 - library.seg.org
Seismic diffractions carry the signature of near-surface high-contrast anomalies and need to
be extracted from the data to complement the reflection processing and other geophysical …
