abstract

The extraction of dispersion relations from recorded seismograms is commonplace, but usually such analysis is confined to a single trace at a time. In exploration seismology, large numbers of traces are available, and in this paper, methods are developed by which a set of traces can be analyzed to reveal dispersion characteristics, i.e., phase and group velocities, and the linear chirp rate. Knowledge of the latter parameter permits compression of signals as a precursor to high-resolution mapping. The techniques are illustrated using both synthetic and real data, the latter being the Love type waves that propagate in coal seams.
