A Complex SVD-Polarization Filter for Ground Roll Attenuation on Multi-Component Data

Abstract

B019 A complex SVD-polarization filter for ground roll attenuation on multi-component data Summary 1 By their very nature multi-component (3C/9C) datasets provide information on the full wavefield and therefore offer new full wave-field solutions for the ground roll problem. Here we introduce a time-domain 3C complex SVD (Singular Value Decomposition) polarization filter that is optimized to remove most ground roll energy whilst preserving the reflected energy. A 3C Eastern European dataset is used to test filter performance on shot gathers. Finally vertical-component stacks from two polarization filters with different design length are compared to a control stack with no ground
