FIELD: hydro acoustics.
SUBSTANCE: technical result is achieved due to neural network system for detection and rapid identification of marine targets, comprising analogue-to-digital converter, recirculator, narrow-band filters, multipliers, integrators, squares, adders, square-root calculators, delay devices, threshold devices, read-only memory, preliminary processing unit, data preparation unit, neural network recognition module implemented in the form of a training unit enveloped by feedback with target type categorizer.
EFFECT: technical result is providing rapid automatic identification of sea targets detected in noise direction-finding mode.
