FIELD: physics.
SUBSTANCE: invention can be used in applied hydroacoustics to protect offshore oil and gas platforms, underwater storages for hydrocarbon raw materials and specialised vessels; water intake structures of electric power plants, including nuclear power plants, from intrusion by potentially dangerous underwater objects: fighting underwater swimmers, combat marine animals, manned and unmanned submarines, as well as in the fish industry: for protecting water intake structures of different industrial structures from intrusion by sea biological objects - fish, maxillopods, jelly fish etc, as well as for controlling passage of commercial collections of sea biological objects through given border.
EFFECT: detection, accurate recognition and accurate determination of spatial coordinates of acoustically nearly invisible underwater objects under conditions with high ambient noise of the sea.
