FIELD: underwater acoustics, applicable for hydrometeorological observations of the sea range water area.
SUBSTANCE: the device has a synchronization and control unit, series-connected hydrophone, preamplifier, communication line, wide-band amplifier, spectrum analyzer unit, spectrum section separation unit, sea noise classification unit, wind speed measuring unit seaway determination unit. The output of the spectrum analyzer unit is connected to the indicator input the output of the spectrum section separation unit is connected to the input of the wind speed measuring unit. The outputs of the sea noise classification unit, wind speed measuring unit and seaway determination unit are connected to the indicator inputs. The controlled input of the synchronization and control unit is connected to the output of the sea noise classification output. The synchrooutputs of the synchronization and control unit are connected to the synchroinputs of the spectrum analyzer, spectrum section separation, sea noise classification, wind speed measuring, seaway determination units. In addition the device has a parametric sound detector, medium nonlinear parameter diagnostics unit, narrow-band filter, acoustic wave spectral analyzer at heterodyne frequencies, logic module. The output of the parametric sound detector is connected to the input of the medium nonlinear parameter diagnostics unit, whose input is connected to the output of the synchronization and control unit, and the output - to the input of the narrow-band filter. The output of the narrow-band filter is connected to the input of the acoustic wave spectral analyzer at heterodyne frequencies. The outputs of the logic module are connected to inputs of the indicator and the dispatcher station.
EFFECT: enhanced truth of the obtained results, expanded functional potentials of the device.
