FIELD: physics.
SUBSTANCE: in a hydroacoustic complex containing N acoustic combination receivers forming a bottom vertically oriented equidistant antenna in which the distance between the acoustic combined receivers is equal to a predetermined error in determining the vertical coordinate (horizon) of the sound source Δz and the number of receivers N=H/Δz (where H is the depth Sea), each of which consists of a hydrophone, a three-component vector receiver and amplifiers connected to them, a telemetry unit whose input is connected to an acoustic output Including combiners of voltage, an analog-to-digital converting circuit, single electronic multiplexing scheme, a modulator and an optical radiator coupled by an optical link to an optical receiver, a data acquisition, processing and transmission system comprising a data acquisition, processing and transmission unit and an access device for digital data networks, an N-channel vertical component calculating unit of the intensity vector, the vertical intensity component of the intensity vector, the N-channel unit for calculating the horizontal components of the intensity vector, the N-channel of calculating the averaged azimuth angle, calculating the averaged azimuth angle, an adder, a complex envelope spectrum analyzer, a complex envelope spectrum analyzer, an N-channel subsystem for forming a one-way directional reception along the vertical power flux, comprising an N-channel block of quadratic detectors of the vertical component of the vibrational vector of speed, N-channel vertical directional power generation unit, N-channel integrator unit.
EFFECT: additional increase in noise immunity of the vertical channel of the elementary combined receiver and the whole complex as a whole, as well as an increase in the range of action.
