MAGNETIC FIELD SIGNAL SOURCE PROPERTY ANALIZING DEVICE, A METHOD, AND A SYSTEM THEREOF WHICH IS DISTRIBUTED IN A WARSHIP FOR APPLYING AN INVERSE QUESTION ANALYSIS METHOD

摘要

PURPOSE: A magnetic field signal source property analyzing device, a method, and a system thereof are provided to have high reliability for an estimating result of a field signal before and after warship drying by accurately estimating distribution of permanent magnetization distributed on the hull of a warship.;CONSTITUTION: A signal receiving part(110) receives a magnetic field signal generated in a warship. A pre-processor(130) partitions a shape of the warship into shape information consisting of a plurality of planes. An inverse question analysis part(150) determines a magnetic dipole distributed on center of the plurality of planes using an inverse question analysis method. A postprocessor(170) calculates the size of a magnetic field signal at a specific location which is separated from the warship using the each magnetic dipole determined in the inverse question analysis part.;COPYRIGHT KIPO 2013;[Reference numerals] (110) Signal receiving part; (130) Pre-processor; (150) Inverse question analysis part; (170) Postprocessor
