Multiple Attenuation after Migration

Multiples can be suppressed in the angle-domain image space after migration. Primaries and multiples have different angle-domain moveout, therefore they can be separated using techniques similar to the ones employed in the data space prior to migration. We use Radon transforms in the image space to discriminate between primaries and multiples. This method has the advantage of working with 3-D data and complex geology. It offers an alternative to the more expensive Delft approach.
