With such approach, multiple stages progressively build the coherent signal model while eliminating the associated interference noise in a signal safe manner. While including priors in the multiple stages artificially enhances the sparsity of the coherent signal in the transform domain, the usage of the higher dimensional transform further enhances natural sparseness, thus stabilizing separation for any acquisition scenario, be it with natural or controlled dithers. We demonstrate our findings using real data from land and towed-streamer surveys, also validating the potential of the proposed approach.Keywords: deblending, land, marine, sparse, optimizationPermalink: https://doi.org/10.1190/segam2021-3584184.1FiguresReferencesRelatedDetails First International Meeting for Applied Geoscience & Energy Expanded AbstractsISSN (print):1052-3812 ISSN (online):1949-4645Copyright: 2021 Pages: 3561 publication data© 2021 Published in electronic format with permission by the Society of Exploration GeophysicistsPublisher:Society of Exploration Geophysicists HistoryPublished: 01 Sep 2021 CITATION INFORMATION Rajiv Kumar, Yousif Izzeldin Kamil Amin, Araz Mahdad, Phillip Bilsby, Anu Narayan, Wouter Gerrit Brouwer, Amr Misbah, and Massimiliano Vassallo, (2021), "Effects of dimensionality of transform domain on multiple stages source separation with prior," SEG Technical Program Expanded Abstracts : 76-80. https://doi.org/10.1190/segam2021-3584184.1 Plain-Language Summary KeywordsdeblendinglandmarinesparseoptimizationPDF DownloadLoading ...
