Abstract
Split-step Fourier migration method was first developed and applied to migrate zero-offset seismic-data by Stoffa et al. (1990). This method is an extension of Gazdag's phase shift migration that accommodates lateral velocity variations. It is based on decomposing the laterally varying slowness function into two components; a mean slowness component and a laterally varying component.
