FIELD: measurement equipment.
SUBSTANCE: hydroacoustic measurement complex comprises N acoustic combined receivers, every of which comprises a hydrophone, a three-component vector receiver and connected amplifiers, a telemetric unit, including voltage dividers, an analogue to digital conversion circuit, a single circuit of electronic multiplexing, a modulator and an optical radiator, connected with an optical communication line with an optical receiver, a system of collection, processing and treatment of information, comprising a unit of information collection, processing and treatment and a device of access to digital circuits of data transmission. By means of acoustic combined receivers, a bottom vertically oriented equidistant antenna is produced, in which the distance between acoustic combined receivers is equal to the specified error of detection of a vertical coordinate (horizon) of the source of sound Δz, a the number of receivers N=H/Δz (where H-sea depth). The information collection, processing and treatment system additionally includes an N-channel unit of calculation of a vertical component of an intensity vector, a unit of determination of a maximum of a vertical intensity vector component, an N- channel unit of calculation of horizontal intensity vector components, an N-channel unit of calculation of an azimuthal unit, a unit of calculation of an averaged azimuthal angle.
EFFECT: reduced error of measurement of an azimuthal angle and a horizon of a source, increased distance of action in process of measurement complex operation in a shallow sea.
