Analysis of P- and S-wave arrival times on harmonic and broad-band vibroseismic signals

The recently developed method of active vibroseismic monitoring is based on the sounding of a geological structure by seismic waves from artificial controlled sources-vibrators. Thus, the changes occurring in the tensely-deformed state of a medium are considered as related to changes of information parameters of wave fields that are established in the medium with long radiation by the vibrator of broad-band sweep or harmonic signals.
