The extraction of direct and scattered ground roll and its removal allowed by interferometry can provide a robust solution for the effects of the shallow geology on surface seismic data. Conventionally, surface waves are estimated implementing a modification of the exact theory of virtual‐source interferometry. For example, we usually apply an approximated version of the interferometric equation that does not require spatial derivatives. This introduces errors and spurious events due to the effect of scatterers outside the integration boundary. In this paper we assess whether or not the use of spatial derivatives adds value to the estimates made using virtual‐receiver interferometry, using both field experiments and synthetic data.Permalink: https://doi.org/10.1190/1.3627999FiguresReferencesRelatedDetails SEG Technical Program Expanded Abstracts 2011ISSN (print):1052-3812 ISSN (online):1949-4645Copyright: 2011 Pages: 4424 Publisher:Society of Exploration Geophysicists HistoryPublished: 08 Aug 2011 CITATION INFORMATION Filippo Broggini, David Halliday, and Ed Kragh, (2011), The contribution of the spatial derivatives to surface‐wave interferometry, SEG Technical Program Expanded Abstracts : 3804-3808. https://doi.org/10.1190/1.3627999 Plain-Language Summary PDF DownloadLoading ..." @default.
