F-37 MULTIPLE SUPPRESSION AND DATUMING WITH AN ANTIALIASED RADON TRANSFORM FOR MARINE 4C DATA 1 Summary. We use Radon transformed common-receiver gathers for pressure and velocity components to suppress the freesurface effects from the data and to datum the results from the sea-floor to the free-surface. The scheme for ghost and multiple suppression is essentially a combination of the work of Soubaras (1996) and a modification of the approach of Amundsen (1999). It is well known that the receiver-side ghost effects can be suppressed by weighted summation of pressure and vertical velocity records. The problem is to estimate the weighting
