METHOD OF DETERMINATION OF SHIP'S SPEED OVER BOTTOM Russian patent published in 1995 - IPC

Abstract RU 2037847 C1

FIELD: hydroacoustics. SUBSTANCE: method of determination of ship's speed over bottom is based on radiating the signal towards bottom in the direction inclined relative to direction of motion, calculating the Doppler parameter and determining the ship's speed by the preset relationship of known and measured parameters, then signal at hyperbolic modulation frequency is radiated; in calculating the Doppler parameter, use is made of information on phase of radiated and reflected signals. EFFECT: enhanced accuracy of determination of ship's speed. 2 dwg
