HORIZONTALLY DEVELOPED RADIO HYDRO-ACOUSTIC SYSTEM OF THE OBJECTS AND MARINE ENVIRONMENT HYDROPHYSICAL AND GEOPHYSICAL FIELDS MONITORING Russian patent published in 2018 - IPC G01H3/00 

FIELD: hydro acoustics.

SUBSTANCE: monitoring system includes the luminal medium pumping waves with the measured information signals nonlinear interaction and parametric conversion working zone, located at the marine environment opposite boundaries three emitters and three receiving units, including by three transducers (hydrophones), which are combined into horizontally arranged triangles with vertices directed opposite to the radiating transducers, connected to them medium pumping emitted signals generation and amplification path and path of the reception, processing and recording of information signals, including the information waves recorder, three lines of correlation and cross-correlation analysis of received signals, and a spectral analysis line, which are connected to the measuring system receiving units through the received signals common switchover and switching unit, system receiving path is further provided with the measuring information switching unit, which is located between the correlation analysis lines outputs and the spectral analysis line input, at that, all the measuring system correlation and cross-correlation analysis lines include sequentially connected units of the two-channel wideband amplification, two-channel measurement of their correlation functions, their mutual correlation functions measurement, multifunctional analysis unit and the common for all three lines a measured information recording unit, at that, the of the complex information analysis unit output through the radio unit is connected to the monitoring system information and analysis center, containing the in-series-connected receiving radio unit, system analysis unit and a transmitting radio unit, which output is connected to the monitoring system radiated signals generating unit via the radio channel.

EFFECT: invention is intended for use in parametric monitoring systems providing the hydrophysical and geophysical fields characteristics monitoring, formed by natural sources, seismic processes and dangerous phenomena (for example, internal waves, strong earthquakes or tsunamis) in a large-scale marine area.
