FIELD: hydroacoustics.
SUBSTANCE: depth is measured by means of hydroacoustics positioned on mobile sea objects. The object speed is determined by radio receiver-indicator and satellite navigational system. The vertical sound distribution is determined and sea ground form is reconstructed, then the sea ground surface is plotted. For method implementation the device is put forward containing radiating and receiving aerials, control unit, valuator, pump conditioner, graphplotter and parametrical emitting tract.
EFFECT: increasing of method reliability.
