An SVD‐polarization filter for ground roll attenuation on multicomponent data

Abstract

By their very nature, multicomponent data provide information on the full wavefield and therefore offer new full‐wavefield solutions for the ground roll problem. Here we introduce a time domain multicomponent Singular Value Decomposition (SVD) polarization filter that is optimized to remove most ground roll energy, while preserving reflected energy. We first test the filter on synthetic data and then on real data for both shot gathers and stacked sections. Finally, we compare our results to an f‐k filtering technique and observe that the polarization filter does a superior job.
