摘要： PROBLEM TO BE SOLVED: To provide a current moment analysis device capable of more accurately determining a current moment compared to conventional cases. SOLUTION: When a measured vessel 5 is made to pass through a neighborhood, a zero cross-point of an output waveform of a submerged electric field sensor 2 is detected. Based on positional information of the submerged electric field sensor 2 and positional information of the measured vessel 5 obtained during detection of the zero cross-point, an intermediate position of a current source of the measured vessel 5 is led out, and based on the intermediate position and the position of the current source (- side), a current source interval L of the measured vessel 5 is determined. A peak-to-peak value Va of the output waveform of the submerged electric field sensor 2 is stored. Next, as the same condition, the output waveform of the submerged electric field sensor 2 at a current value I [A] is led out by simulation, and a peak-to-peak value Vb at that time is determined. In the condition, a current value I=Va/Vb achieving the situation where the waveform is the peak-to-peak value Va is determined. Thus, by determining the current value I of the measured vessel 5, the current moment (L×I) of the vessel is determined. COPYRIGHT: (C)2011,JPO&INPIT
