Abstract
A brief review of investigations in the field of coherent seismoacoustics is presented, and the general requirements for seismoacoustic wave radiators intended for solving problems of remote sounding are formulated. The principle of operation of a novel high-power radiator created at the Institute of Applied Physics, Russian Academy of Sciences, for generating low-frequency seismic waves is described, and the results of the analytical and numerical modeling of this radiator are presented. The main element of the radiator is a piezoelectric cylinder executing bending vibrations in a well filled with water. The concept of sectioning the radiating cylinder for increasing the efficiency of excitation of various radiator modes and improving the matching the radiator with the medium is formulated. The results of the field measurements of the space-time structure of the seismic field generated by the sectioned radiator are presented. On the basis of these measurements, estimates of the power, efficiency, and quality factor of the radiator are obtained.
