Abstract. In this work, an effective technique for the measurement
of seismic wave propagation velocity in the real geological medium is presented.
The propagation velocities of seismic waves vary in different types of
geological media from 100 m/s to 6800 m/s. Due to this, it is necessary
to evaluate the propagation of the seismic wave front between the different
points in the real media. The signal time delay is determined by locating
the peak in the cross-correlation function, obtained by the correlation
of the signals from these sensors. The efficiency of this method is illustrated
with experimental results.
MERENJE BRZINE PROPAGACIJE SEIZMIČKIH
TALASA U REALNOM MEDIJUMU
U ovom radu opisana je efikasna tehnika određivanja brzine propagacije
seizmičkih talasa u realnom geološkom medijumu. Brzina propagacije seizmičkih
talasa varira u zavisnosti od tipa geološkog medijuma i nalazi se u opsegu
od 100 m/s do 6800 m/s. Zbog toga je neophodno da se odredi propagacija
fronta seizmičkih talasa između različitih tačaka u realnom medijumu. Kašnjenje
signala je odredjeno lociranjem tipa kroskorelacione funkcije dobijene
korelacijom senzorskih signala. Efikasnost metode je ilustrovana eksperimentalnim
rezultatima.
