Initially the data are slanted‐stacked along the offset direction for each shot and then organized into common offset ray parameter sections (p→o). Each constant p→o section is migrated separately in a manner similar to a poststack migration procedure using Gaussian beam method based on microlocalization, except for an additional term related to the offset ray parameter using an interval velocity in depth. It extends the Gaussian beam method to migrate the plane wave gathers and combines the numerous advantages of the plane wave migration and Gaussian beam migration.Permalink: https://doi.org/10.1190/1.2792923FiguresReferencesRelatedDetailsCited ByA Time-Domain Seismic Imaging Method With Sparse Pulsed-Beams DataIEEE Transactions on Geoscience and Remote Sensing, Vol. 60Pulsed-beams migration with windowed Radon transform framesRam Tuvi, Zeyu Zhao, and Mrinal K.
