Seismology; Seismic or acoustic prospecting or detecting; Processing seismic data, e.g. analysis, for interpretation, for correction; Effecting static or dynamic corrections on records, e.g. correcting spread; Correlating seismic signals; Eliminating effects of unwanted energy specially adapted for seismic systems using continuous agitation of the ground, e.g. using pulse compression of frequency swept signals for enhancement of received signals Correlating received seismic signals with the emitted source signal
