Modulated-Shot Migration

This paper presents a new migration algorithm, which is able to produce p-indexed gathers and a final image equal to that of a shot-record migration at less cost. This algorithm uses shot composition, just as plane-wave migration but by using modulation rather than time delays on the original shots. This allows using only a minimal number of composite shots for the migration.
