Super-resolving Seismic Locating Algorithm for Reflected Waves Hodographs Approximation

The authors develop original seismic locating technology in a number of their papers. The present paper shows that application of super-resolving radio-locating methods ideas in the proposed technology allows solving actual problems of seismic images construction in a new way. In particular, it is possible to solve the problem of high resolution and accuracy approximation for the phase hodographs series of the waves reflected from seismic section boundaries. The developed super-resolving seismic locating algorithm ensures fulfillment of the requirements in every narrow space-time band, revealed by the considered technology on the seismogram as the hodograph location. The series of the reflected waves phase hodographs, built using the areas of the seismogram, characterizes the family of the investigated medium layers for the fixed location of a seismic vibrations source. Application of the proposed algorithm ensures, with a prescribed accuracy, building sets of the reflected waves phase hodographs, separating close or interfering wavefronts. The locating relief obtained by application of the algorithm allows finding and tracing even not observed visually systematic vibrations on the seismogram. Thus, the approximation accuracy and resolution degree of the various waves phase hodographs series can be increased. It is shown that the result can be achieved using a concrete seismogram or the improved seismogram obtained fromthe set of seismograms of observation profile.
