In the history of multiple removal, algorithms have been based on wo differentiating properties: moveout and predictability. If prima-ies and multiples show different moveout behavior, algorithms are vailable that allow separation of primaries and multiples in a trans-orm domain. Successful moveout-based methods use the Radon ed crosscorrelation WCC and transforms primary energy into its focal point around zero time. After an imaging step, the result is in-put to the inverse focal transform, leading to the desired multiple-free output. Initial results indicate that combined weighted convolu-tion and weighted crosscorrelation may lead to new opportunities in multiples removal. The forward focal transform involves a correlation process of wavefields. In that respect, it is related to research carried out by Sunmaging of multiple reflections. J. Berkhout1 and D. J.
