Coherence-guided interpolation performs trace interpolation based on a time and space-varying dipscan analysis of neighboring traces. Coherency measurements are taken over test dips within overlapping time gates. Interpolated data segments are then constructed based on the maximum coherency-weighted combination of individual data segments.

This method depends only on local input data support, is capable of overcoming aliasing, and can create new shots and receivers along or across existing shots and receiver lines, as in the example below.
