Abstract: PURPOSE: An active deperming system and a method at the same are provided to reduce a time for processing deperming by selecting a deperming current in step and processing it. CONSTITUTION: An active deperming system includes a magnetic material, an Z-coil, a deperming coil, a magnetic filed measurement unit, a driving power source(25), and a active deperming processing unit. The Z-coil eliminates the vertical direction magnetic field of the magnetic material. The deperming coil removes magnetic filed in vertical and horizontal direction. The magnetic filed measurement unit measures the magnetic filed signal of the magnetic material. A driving power source supplies current to the deperming coil. The active deperming processing unit estimates the deperming current applied to the deperming coil by receiving a magnetic filed signal from the magnetic filed measurement unit, and it controls the driving power source to apply the estimated deperming current to the deperming coil.

Abstract: PURPOSE: A device and method for analyzing a characteristic of a magnetic source on a naval ship are provided to increase reliability for predicting a result before/after building a naval ship. CONSTITUTION: A signal measuring unit(110) measures a magnetic field signal generated in a naval ship. A pre-processing unit(130) partitions the body surface of the naval ship into face elements. A magnetic charge is distributed on the body surface of the naval ship in a discrete type. Measured data are set as target data for inverse problem analysis. An inverse problem analyzing unit(150) determines the strength of a magnetic charge distributed in a node of each element based on the magnetic field signal and shape information of the naval ship. A post-processing unit(170) calculates the strength of the magnetic field at any location of the naval ship based on the magnetic charge distribution.
