Incomplete data, unknown source-receiver signatures and free-surface reflectivity represent
challenges for a successful prediction and subsequent removal of multiples. In
this paper, a new method will be represented that tackles these challenges by combining
what we know about wavefield (de-)focussing, by weighted convolutions/correlations,
and recently developed curvelet-based recovery by sparsity-promoting inversion (CRSI).
With this combination, we are able to leverage recent insights from wave physics towards
a nonlinear formulation for the multiple-prediction problem that works for incomplete
data and without detailed knowledge on the surface effects.
