... the robustness of time migration with the data enhancement properties of multi- parameter stacking. Due to the latter property, it is particularly well suited for subsalt imaging. The presented method is based on the generation of partially time-migrated gathers, i.e., prestack data in the common scatterpoint...

.... Prestack partial migration is the process that, in addition to NMO, yields the transform of every constant offset section into the corresponding zero-offset section. The intention is to sup- press the dip-filtering effect introduced by stack, and the process is therefore alternatively named dip moveout...

Though prestack partial migration schemes only allow one-dimensional velocity distributions they turn out to be very attractive from...

... surface refraction velocity analysis was necessary. Existence of some of the steeply dipping reflectors in the area also require prestack partial migration (DMO) processing and an algorithm was written in the f - k domain (Hales, 1984) for this project. The final processed data clearly map several key...
