... Summary Local slant stack is a useful method in extracting angle domain information. However, it’s rather expensive to use in 3D illumination analysis. Here, we present an efficient method of directional illumination analysis for 3D case using local exponential frames. To get the local...

... algorithm was applied to a 3-D GOM deep water dataset and was compared with Kirchhoff PSDM. A wave equation illumination study, including the computation of total and directional illumination intensity, was further carried out to investigate the origins of subsalt imaging shadow zones and amplitude...

Introduction Advances in seismic technology, particularly in prestack depth migration, have made significant improvement in providing reliable high-resolution images for complex structures. velocity model propagator receiver migration illumination artificial intelligence directional illumination...

... Summary Directional illumination and acquisition-aperture efficacy are evaluated through wave equation-based beamlet wavefield propagation. Beamlet decomposition with Gabor-Daubechies frame provides localizations in both space and direction of wavefields. The image conditions in beamlet...
