Abstract
In this paper, we briefly overview the last-decade studies in the field of coherent seismoacoustics, carried out at the Institute of Applied Physics of the Russian Academy of Sciences (IAP RAS). Various schemes of the use of powerful hydroacoustic transmitters as effective seismic sources, as well as theoretical models for their analysis and numerical modeling are comparatively described. Methods for the high-resolution seismoacoustic imaging of underground inhomogeneities are discussed. These methods are based on the use of coherent signals, in particular, coded by large pseudorandom sequencies. The special attention is paid to the results of recent field experiments demonstrating the advantages and new capabilities of coherent methods of seismoacoustic diagnostics at different depths from tens of meters up to tens of kilometers.
