SYSTEM FOR　POSITION REFERENCE OF VESSEL BY USING SOUND SOURCE LOCALIZATION AND POSITION REFERENCE METHOD

摘要

The present invention relates to a ship's position based on the technique using the sound source position estimation , the vessel position estimate of the is transmitted from the plurality of sound signal generating device is located in the water in the device to estimate the sound source at the same time calculates the relative position of the sound signal generation apparatus, the absolute position of the ship on the relative position information of the calculated acoustic signal generator and the acoustic signal generation using the absolute position information of the device is characterized in that for estimating the absolute position of the vessel . ;
