Abstract

We derive a new, stable, true-amplitude cross-correlation type imaging condition for shot-profile migration by changing the source of the downgoing wavefield. Essentially this modification deconvolves the spatial response of the seismic point source and restores the amplitudes in the final image. Numerical examples demonstrate that the resulting common-angle gathers give the correct amplitude-versus-angle behaviour for a simple model.
