If the small-reflection-coefficient approximation holds, then the approximation holds, and the multiples can be removed by ordinary (i.e., linear time-invariant) deconvolution. In other words, the small-reflection-coefficient approximation justifies the use of ordinary deconvolution. For this reason, a sequence of time gates is chosen on the actual seismic trace. The choice is made on the supposition that within each gate, the small-reflection-coefficient approximation holds. A deconvolution operator is computed for each gate. The deconvolved trace is made up of all the deconvolved gates along with appropriate interpolation between any two adjacent gates.
