摘要

摘要: 为增强舰船的磁性防御能力需要定时对其进行消磁处理，这就要求技术人员在舰船消磁工程中准确，迅速地分析测磁传感器数据。该文模拟点阵式大平面法采集的测磁传感器数据，依照舰船磁场的磁偶极子阵列数学模型实现磁场数据的深度换算；将空间点阵式的磁偶极子阵列模型数据转化为2D数组数据，进行模型的空间面显示；利用磁场-灰度映射关系实现模型的4D可视化描述，为优化舰船磁场模型提供了准确且直观的依据；通过对测量面和换算面磁场数据的可视化描述，绘制其3D视图、等强线图和剖面图，为消磁技术人员监控测磁传感器工作和进行消磁电流决策，消磁效果评价提供了有力依据。

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.
