Multichannel processing to remove seafloor multiples; the operator designed on a trace with offset x1 is used to deconvolve the first multiple on the trace with offset 2x1, the second multiple on the trace with offset 3x1, etc. These all involve the same angle of incidence (see Figure R-2) and hence the same reflectivity.
