摘要: Ideally, full prestack migration involves a 4-D integration along the source and receiver coordinates. Obviously, for cross‐spread data (typical for land acquisition) this 4-D integration cannot be effectuated. An analysis is presented of the resolution and amplitude behavior of full prestack migration, applied to cross‐spread data. Moreover, a proposal is made to modify operators that partly compensate for the diminishing effects of the cross‐spread aquisition geometry on amplitudes and resolution.
