Paper Summary
As an alternative to the conventional high-resolution Radon transform, we propose a time-domain approach to transform a gather of pre-stack seismic data into a gather of highly-resolved traces in the transformed domain. Using a range of various velocity functions in a standard NMO correction routine we iteratively identify the most energy-bearing functions and transfer the corresponding stackable energy consecutively. Iso-moveout functions can be used to avoid the distortions related to the NMO stretching. Application to synthetic and real data has shown improvements in resolution and performance. Higher resolution results in less ambiguous aperture compensation and therefore more successful reconstruction of stackable seismic events in the large gaps of missing data. This feature helps to improve the accuracy of modeling multiple events particularly in the near offset zone.
