FIELD: physics.
SUBSTANCE: hydroacoustic probing of the investigated region is carried out using radiation of intense acoustic signals, less intense low-frequency acoustic signals and pumping waves in the direction of the bottom. Reflected signals are received and used for prediction purposes. Investigations are carried out using a submarine geophysical vessel having an anaerobic main propulsion plant. The submarine vessel is laid on the ground, thereby achieving the minimum level of its underwater hydroacoustic and hydrodynamic fields. Information features also used are the shape of the spectrum of the relatively narrow and wide frequency bands, the shape of the spectrum of high-frequency modulation acoustic and electromagnetic frequencies, and the signal-to-noise ratio.
EFFECT: high reliability of predicting mineral deposits.
