UNDERWATER SITUATION PRESENTING SYSTEM Russian patent published in 2015 - IPC G01S15/00 G08B19/00 

FIELD: electricity.

SUBSTANCE: underwater situation presenting system is related to special-purpose equipment and may be used for detection and identification of underwater objects as well as for signalling and annunciating appearance of facilities of marine economical activities (sea port aquatic areas, sea terminals on hydrocarbons production and transportation, waterworks, etc.), unknown small-size vehicles or divers, as well as for detection and tracking of icebergs. The underwater situation presenting system consisting of a group of multi-beam echo sounders, hydroacoustic transceivers, which n-beams are shaped with a transceiving antenna so that sector scanning is performed in the aquatic area with facilities of marine economical activities, at that transceivers are united with acoustic signals processing unit installed at the dispatcher station at the facility of marine economical activities and connected to the processor with installed automatic detection and tracking software, which is coupled to the data display unit, at that each transceiver is connected by fibre-optic cable to the acoustic signals processing unit installed at the dispatcher station at the facility of marine economical activities, transmitting and receiving channels are coupled to the acoustic signals processing unit intended to generate transmitted signals, recording and processing of the received signals respectively; the acoustic signals processing unit connected to the processor with installed automatic detection and tracking software, which is coupled to the data display unit is distinguished by the fact that the each multi-beam echo sounder contains a parametrical profile recorder, at that pumped antennae of the parametrical profile recorder at drifting or anchored buoys at different horizons within the aquatic area depths at distance of 8000 m at most from each other.

EFFECT: potential in-line identification of the unknown underwater object location, identification of the underwater object and display of an unauthorised underwater object at the monitor installed at the facility of marine economical activities.
