SUBSTANCE: invention relates to the field of hydroacoustics and can be used for construction of a scalable system for detection and classification of marine targets with elements of artificial intelligence. System includes a main system comprising emitter (3) and two receiving transducers (4) and (5), formed in the marine environment working area (7) of nonlinear interaction and parametric conversion of pumping waves and information waves in form of two horizontally spaced in reception points and matched at the point of emission of parametric antennae, radiating path (1) connected to emitter (3), comprising a receiving radio unit, two pumping signals generators, series-connected power amplifier and an amplifier output matching unit with an underwater cable and an emitter, receiving path (2) connected to two receiving transducers, including series-connected two-channel broadband amplifier, phase meter, a converter of frequency-time scale of signals into a high-frequency region, a narrow-band spectrum analyzer, outputs of which are connected to a recorder and a transmitting radio unit, information analytical center (IAC) comprising a system analysis unit, the input of which is connected through the receiving radio unit to the output of the transmitting radio unit of receiving path (2), and the output of the system analysis unit through the transmitting radio unit is connected to the input of radiating path (1) receiving radio block. Main system is scaled with n additional systems installed on adjacent and (or) remote water areas. Each additional system comprises emitters (3.1...3.n) and two receiving transducers (4.1...4.n) and (5.1...5.n), working zones (7.1...7.n) formed in the marine environment, emitting channels (1.1...1.n), receiving paths (2.1...2.n), IACs (18.1...18.N), which are similar in terms of internal content and external connections to the main system. In addition, the scalable system further includes a single information and analysis center (SIAC) which controls the operation of the entire system in accordance with long-term marine monitoring tasks and conditions, the inputs of which are connected via radio communication channels to the IAC outputs of the main and n additional systems, and which outputs are connected via radio communication channels to inputs of radiating paths of main and n additional systems, respectively.
EFFECT: enabling creation of a radio-hydroacoustic system for transmitting information waves from the marine environment to the atmosphere and back, long parametric reception of waves in the sound and infrasound frequency bands, high capacity of information on sources of fields of different physical nature and hydroacoustic conditions of propagation of signals in the marine environment, adding and updating libraries of portraits of classification objects, faster recognition, high probability of classification of surface and underwater targets, wider range of recognized objects.
