AUTOMATED SYSTEM FOR SIMULATING CHARACTERISTICS OF HYDROACOUSTIC CHANNELS AND RECEIVING WAVES OF DIFFERENT PHYSICAL NATURE IN MARINE ENVIRONMENT Russian patent published in 2025 - IPC G01H3/00 

FIELD: hydroacoustics.

SUBSTANCE: invention relates to hydroacoustics and can be used in systems for marine monitoring of waves of different physical nature, created by natural and artificial sources. In particular, for efficient formation of spatially developed parametric antennae in marine environment taking into account multibeam propagation of waves in hydroacoustic channels with variable characteristics of boundaries and environment. In the automated system for simulating the characteristics of hydroacoustic channels and receiving waves of different physical nature in the marine environment, the system parameters control and adjustment unit is additionally introduced, which input is connected to the output of the narrow-band spectrum analyser of the signal receiving, processing and recording channel, and the output is connected to the input of the pumping signal generator of the low stabilized frequency of the signal generation and amplification channel. In addition, the structure of the system includes a channel for simulating characteristics of hydroacoustic channels, which contains series-connected unit for automated data preparation, a unit for simulating characteristics of the hydroacoustic channel, a unit for accumulating and analysing information on parameters of the hydroacoustic field. Input of the automated data preparation unit is connected to the output of the unit for controlling and adjusting parameters of the system, and the output of the unit for accumulating and analysing information on parameters of the hydroacoustic field is connected to the input of the unit for controlling and adjusting parameters of the system.

EFFECT: increased efficiency of parametric antenna formation in marine environment taking into account multibeam propagation of waves in hydroacoustic channels with variable characteristics, which increases the volume of the working zone of nonlinear interaction and conversion of waves and, as a result, increases the range of parametric reception of waves.
