Abstract
Vibrosies exploration seismology is leading geophysical method. The Recent hardware and technology developments allow seismic acquisition for detail near surface imaging. The light seismic vibrator driven by linear synchronous motor may serves as an alternative to hammer or standard heavy hydraulic vibrosource for shallow depth engineering studies. Advantages of electric vibrator includes wider output signal spectrum (up to 1KHz), shear wave mode operations with all kinds of comprehensive signals such as pseudorandom , adaptive and broadsweep sweep signals. The first field experiment with lightweight vibrosource was carried out in urban environment of Moscow City. Results of field experiment and data processing are presented in this paper.
