SYSTEM AND METHOD FOR SEISMOLOGICAL SOUNDING

摘要

Systems and methods for seismological sounding with acoustic signals and, more particularly, systems and methods for performing geophysical surveys using spread spectrum acoustic waves generated by non-impulsive sources. A spread spectrum signal is generated and coupled to a medium that is to be sounded for propagation of an acoustic wave through the medium. One or more return signals are received from the medium that are generated by interaction between the acoustic wave and the medium. The return signals are possessed to obtain seismic sounding data describing the structural features of the medium.
