摘要
斜航向上舰船感应磁性磁场分离是舰船磁场分析中的一个难点.针对舰船龙骨下方典型测量点上的磁场特征特殊形态展开分析,可方便明晰地解决这一问题.根据相差180°的两个航向上的磁场测量数据,可分离出舰船纵向和横向感应磁性磁场的总和.在舰船龙骨下典型测量点上,舰船纵向和横向感应磁性磁场总和的纵向和垂向分量来源于纵向感应磁性,横向分量来源于横向感应磁性.最终,实现了斜航向上舰船纵向和横向感应磁性磁场的分离.
The decomposition of ship induced magnetism and magnetic fields in oblique courses is a difficult point in ship magnetic field analysis.The method based on the special situation of the magnetic signature at the typical measurement points under the keel of ship can solve this problem easily and clearly.According to the magnetic field measurements in two headings of 180°difference,the sum of the longitudinal and the transverse magnetism of the ship can be separated.At the typical measurement points under the keel of a ship,the longitudinal and vertical components of the magnetic fields of the sum of the longitudinal and the transverse magnetism of the ship come from the longitudinal induced magnetism,and the transverse component of the magnetic fields comes from the transverse induced magnetism.Finally,the decomposition of ship induced magnetism and magnetic fields in oblique courses is realized.
