Residual Migration: Two Approaches
, by Stewart A. Levin and Daniel H. Rothman
In SEP-35 Rothman, Levin, and Rocca analzed some practical aspects
of residual migration. In that article finite differences were
discussed but not implemented. Since then a residual finite difference
migration has been written and applied to the same input of data of
the previous residual Kirchkoff examples. Additional examples of
residual Kirchkoff migration have also been generated. The results of
the two approaches are, as expected, quite similar with finite difference
exhibiting slightly better amplitude control.
