HYDRO-ACOUSTIC ZONE GRAPH Russian patent published in 2004 - IPC

FIELD: technology for determining range of effect of hydro-acoustic systems.

SUBSTANCE: device has calculator of trajectories of acoustic beams, block for data about depth of hydro-acoustic antenna and memory block for recording sound speed in sea environment. Zone graph also has serially connected block for memory of object hydro-acoustic fields, first and second outputs of which are information-connected to system for vibroacoustic control of object and to hydro-acoustic system of object with flexible extensive towed antenna. Also included are calculator of distances of detection of object by observer, block for comparing distances of detection of object by observer and distances of detection of object of observer, indicator of areas of mutual detection. Also included are block for calculating hydro-acoustic interferences of observer, memory block for technical characteristics of hydro-acoustic means of observer, block for calculating interference resistance of hydro-acoustic antennae of observer, block for calculating threshold of detection of detectors of observer, block for calculating losses during dispersion, control block.

EFFECT: higher efficiency.
