Abstract
Employing appropriate high-frequency approximations, we find that frequency-wavenumber migration of spherically corrected data coincides with Born inversion for the reflectivity function. We consider zero-offset seismic data in a 2.5-dimensional medium that consists of a homogeneous reference velocity with embedded reflectors. For marine data, where the pressure is measured, migration and inversion are identical. For land data, where vertical particle velocity is measured, modifications are required in order to match inversion and migration. The modifications become important only if dips larger than 30 degrees are to be migrated.
