    Abstract
  • In order to enhance magnetic defense capability,the magnetic field of ship must be degaussed termly.We obtain the conversion of the magnetic field from the practical measuring depth to normal measuring depth, via the magnetic dipole model of ship′s magnetic field. Through converting the model data from the format of spatial points to that of 2D array, the model′s spatial pattern is plotted; and by using the mapping relation between magnetic intensity and gray scale,4D visualization of the model is implemented to provide an exact and direct approach for optimization of the model. The visualization of ship′s magnetic field in both practical measuring depth and normal depth as well as the 3D graph, isodynamic line map and section offer degaussing operators clear instructions to monitor the magnetic-measurement sensors, decide on the intensity of degaussing current, and evaluate the the degaussing effect.
