FIELD: hydro acoustics.
SUBSTANCE: invention relates to hydro acoustics. Proposed device comprises radiating and receiving transducers arranged in marine environment, transmitting path, receiving cycle, neuron network module and control unit. Transmitting path contains a stabilized frequency pumping generator, a power amplifier and a matching unit. Receiving channel comprises a broadband amplifier, a frequency-time converter, a spectro-analyser and a recorder. Control unit comprises preliminary processing unit and neuronet recognition module. Preliminary processing unit consists of a filter and a data preparation unit. Neural network recognition unit comprises target type categorizer, training unit.
EFFECT: providing long-range parametric reception of waves in the sound and infrasound frequency bands with correction of the process of generating emitted pumping signals of the medium in accordance with the tasks and conditions of long-term marine monitoring, as well as recognition (classification) of detected objects based on computer operations of artificial neural networks using preliminary information compression on object and replenished libraries of mathematically processed images of spectrograms of targets.
