(2005, 2006, 2007). In order to demonstrate the ability of the method for imaging of complex geological structures with steeply dipping strata and faults, we apply it to the Marmousi and Pluto synthetic data sets. We also test the method in situations where synthetic zero‐offset input data are multi‐valued because of caustics of different geometrical structure and, in particular, because of low‐velocity inclusions. In the case of a low‐velocity Gaussian lens we observe dimming and distortion on the migration image of a reflector underneath the lens and study this phenomenon in more detail.Permalink: https://doi.org/10.1190/1.2792916FiguresReferencesRelatedDetailsCited byA fast space-time-domain Gaussian beam migration approach using the dominant frequency approximationPetroleum Science, Vol. 19, No. 4A space-time-domain adaptive focused beam migration method using the dominant frequency approximationD.
