Sonar system to detect moving recessed sound source and measuring its COORDINATE IN SHALLOW WATER

摘要

The sonar measuring system comprising N acoustic combined receivers, each of which consists of a hydrophone ternary vector receiver and associated amplifiers, telemetry unit having an input coupled to an output acoustic combined receiver comprising voltage dividers, an analog-digital transforming circuit, a single circuit electronic multiplexing, modulator and an optical transmitter, an optical communications line connected to the optical receiver, the system of collection, Grain heel and transmitting information containing unit for collecting, processing and transmitting information, the input of which is connected to the output of the optical receiver, and an access device to digital data transmission networks, characterized in that the measuring complex by N acoustic combined receivers are formed two bottom vertically oriented equidistant antenna in each of which the number of elements is equal to N / 2, the local coordinate system of the combined acoustic receivers are aligned, the distance between the vertical ant nnami l λ, wherein the wavelength λ- to lower frequency operation range of noise emission sound source, the distance between the acoustic receivers combined equal to the predetermined error determination vertical coordinate (horizon) stereo source Δz, and the number of receivers at each antenna N / 2-h / Δz , h = zz, z, and the upper horizons znizhny likely location of the sound source, forming a detection corridor, a system for collecting, processing and displaying information entered further N-channel calculating unit vector vertical component int
