FIELD: hydroacoustics.
SUBSTANCE: invention relates to hydroacoustic technology, in particular to the onboard equipment of autonomous uninhabited underwater search vehicles of light and medium class of modular design. Essence: the use of a receiving linear antenna array made it possible to reduce the number of piezoelectric converters in the antenna and, as a result, simplify the equipment of the receiving path, and the introduction of a stepper drive into the device provided a circular view in the vertical plane. The possibility of obtaining a “shadow image” made it possible to increase the efficiency of detecting bottom and near-bottom objects.
EFFECT: increasing efficiency of detecting bottom and near-bottom objects and simplifying the equipment of the receiving path.
