摘　　要：从控制潜艇磁性的源头出发,根据潜艇高空磁场与磁偶极子磁场的等效性,以及磁偶极子磁场与电流环磁场分布的一致性,提出一种基于远场等效磁矩的磁防护方法。通过布设简单补偿绕组,直接补偿潜艇等效磁矩,从而降低潜艇远场磁场。仿真实验结果表明,该方法可有效降低潜艇的远场磁场,提高潜艇对抗航空磁探的能力,为实际潜艇的远场磁防护提供了一种新的思路和技术手段。Starting from controlling the magnetic source of the submarine, according to the equivalence of the submarine＇s aerial field and the magnetic dipole＇s field,as well as the coherence of the magnetic dipole＇s field and the current loop＇ s field,one novel magnetic defense method based on the far field equivalent magnetic moment was founded. By laying simple compensation loops,the equivalent magnetic moment can be compensated directly,and the far field of the submarine can be reduced. The simulation experiment＇s result showed that the method can reduce the far field of the submarine effectively,which can improve the ability of the submarine to resist the aerial magnetic detection and support a new idea and a novel technology means for the actual submarine＇s far field＇s magnetic defense.
