HYDRO ACOUSTIC MEASUREMENT HARDWARE COMPLEX CARRIER Russian patent published in 2011 - IPC B63B22/00 G01S15/02 

FIELD: transport.

SUBSTANCE: invention relates to hydro acoustics and may be used for hydro acoustic analysis of noise radiation in natural water reservoir. Proposed hardware complex carrier comprises buoy made up of elongated torpedo-like hull with acoustically permeable fairing with hydrophone arranged at its center, while positive buoyancy chambers are arranged at bow and stern parts. Said buoy houses components for preliminary conversion of signals. note here that hydrophone output is connected via said components to processing equipment arranged outside said buoy. Depth transducer is arranged outside said buoy. Relation between horizontal and vertical axes of torpedo-like buoy makes not less that five. Angle between beams from hydrophone sensitive element to edges of positive buoyancy chambers makes at least 140°.

EFFECT: reduced hydrodynamic component of noise in measurements in water flow.
