Spatial dynamics of frequency-temporal characteristics of seismic waves from powerful vibrator

The given work is aimed at the analysis of features of spectral-temporal functions (STF), describing vibrational seismograms from powerful vibrators in the near and far zones. The spectral characteristics of P- and S-waves in a far zone at distances of 50, 320, 355 km have been analyzed. The phenomenon of redistribution of oscillation levels between P- and S-waves with respect to a distance has been analyzed too.
