The broadband sensitivity kernel is validated by the directly measured sensitivity map. Based on this kernel, we propose a new wave‐equation migration velocity analysis approach particularly for plane‐wave source migration. This method avoids the expensive local angle or offset decomposition. Numerical method based on the one‐way propagator is designed to calculate the sensitivity kernel. Using a simple 2D synthetic data set, we demonstrate the potential application of this new method in migration velocity analysis.Permalink: https://doi.org/10.1190/1.3255630FiguresReferencesRelatedDetailsCited BySensitivity-kernel-based tomographic migration velocity analysis using reverse time migration angle-image gathersGEOPHYSICS, Vol. 80, No. 3Velocity analysis using shot‐indexed sensitivity kernels: application to a complex geological modelYaofeng He and Xiao‐Bi Xie21 October 2010 SEG Technical Program Expanded Abstracts 2009ISSN (print):1052-3812 ISSN (online):1949-4645Copyright: 2009 Pages: 4338 publication data© 2009 Copyright © 2009 Society of Exploration GeophysicistsPublisher:Society of Exploration Geophysicists HistoryPublished: 14 Oct 2009 CITATION INFORMATION Hui Yang, Xiao‐Bi Xie, and Yaofeng He, (2009), Velocity analysis for plane‐wave source migration using the finite‐frequency sensitivity kernel, SEG Technical Program Expanded Abstracts : 3670-3674. https://doi.org/10.1190/1.3255630 Plain-Language Summary PDF DownloadLoading ..." @default.
