FIELD: instrument making.
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-digital transformation circuit, a single circuit of electronic multiplexing, a modulator and an optical radiator, connected with an optical communication line to an optical receiver, a system of information collection, processing and transfer, comprising a unit of information collection, processing and transfer, and a device of access to digital networks of data transfer. N acoustic combined receivers form a bottom vertically oriented equidistant antenna, in which the distance between acoustic combined receives equals to the specified error of detection of a vertical coordinate (horizon) of a sound source Δz, and the number of receivers N=H/Δz (where H-sea depth). The system of information collection, processing and display additionally includes an N-channel unit of calculation of a vertical component of an intensity vector, a unit for detection of maximum of a vertical component of an intensity vector, an N-channel unit for calculation of horizontal components of an intensity vector, an N-channel unit of calculation of an azimuthal unit, a unit to calculate averaged azimuthal angle.
EFFECT: reduced error of azimuthal angle and source horizon measurement, and also increased distance of action when a measurement complex operates in a shallow sea by increased aperture of its measurement system.
