DOI: 10.1109/lgrs.2021.3107722
Abstract: Ground roll noise is a common type of seismic noise arising from land acquisition. Suppressing ground roll noise has long been a challenging problem due to the strong coupling between ground rolls and reflection signals.… read more here.

DOI: 10.1109/tgrs.2021.3110303
Abstract: Ground-roll attenuation is very challenging because of its high amplitudes and overlapping frequency content with desired signals. A particular challenge is to recover weak reflections underneath strong masking ground-roll. We propose a dual-filter bank setup… read more here.
