FIELD: physics.
SUBSTANCE: disclosed is a computer-implemented data processing method involving reception of a collection of traces corresponding to signals received over time at multiple locations due to reflection of seismic waves from subsurface structures. A measure of correlation between the traces is calculated as a function of a set of wavefront parameters, which determine respective kinematic corrections to be applied in aligning the traces. A matrix having at least three dimensions is generated, wherein the elements of the matrix include the calculated measure of correlation. Using the matrix, values of the wavefront parameters are identified automatically or interactively along the time axis or along selected horizons to maximise the measure of correlation, and a seismic image of the subsurface structures is generated by aligning and integrating the traces using the kinematic corrections which are determined by the identified values of the wavefront parameters.
EFFECT: high accuracy of probing results.
