HYDROACOUSTIC METHOD OF PROCESSING FISHING INFORMATION Russian patent published in 2016 - IPC G01S15/96 

FIELD: fishing and fish farming.

SUBSTANCE: sonar processing method of fishing information includes the detection of fish accumulations sonar reception and data display autonomous sensors acoustic coupling mounted on the trawl, prompting trawl for fish cluster as an antenna sonar used spherical antenna on the basis of which is formed by a spherical set of directional characteristics, which provides simultaneous coverage space with respect to the provisions of the body of the fishing vessel, the detection of fish aggregations performed nasal directivity proactively during the movement of the fishing vessel, automatically measured distance to the fishery cluster, measured the spatial position of the fishing cluster relative to the direction of motion sonar measured remotely depth dive fish aggregations is determined the backs directivity spherical antenna spatial position of the trawl and displayed at the same time the position of the sonar and fish clusters compared submergence fish clusters with a diving depth of the trawl and set immersion depth equal to the depth of immersion of the trawl fishery cluster and direction of movement of the trawl is aligned with the direction of the sonar on the spatial position of the fishing cluster.

EFFECT: increased accuracy of pointing trawls to fish aggregations.
