When upcoming body waves travel through a heterogeneous near-surface region, the continuity of the wavefront can be diminished by scattering. We discuss a multichannel method to predict and subtract near-receiver scattered waves, such that the continuity and trace-to-trace coherency of wavefronts increases. We apply this method to a part from a field-data set which was acquired in an area with significant near-surface scattering. We show that the method increases trace-to-trace coherency in a reflection event. Moreover, application of our method improves the results obtained from application of a dip filter only, because we remove parts of the scattered wave with apparent velocities that are typically passed by the pass-zone of the dip filt...
