摘　　要：对潜艇进行磁探仪探测,需了解潜艇的磁特性模型。潜艇磁性物质分布复杂,直接用解析方法求解其磁场相当困难。经过近几十年的发展,目前已经得到了多种有效的潜艇磁场建模方法。本文分析了目前潜艇磁场建模的几种方法,对各种方法的基本原理进行阐述,并对其适用范围进行分析。最后对潜艇磁场数学模型的选择进行了说明。Model of submarine magnetic field should be known when detecting the submarine by use of magnetic anomaly detection（MAD）.Submarine magnetism substance distributes complexly,so it is very difficult to evaluate the magnetism using analytic method directly.A few effective methods on magnetic field modeling of submarine have been gained by development in the newly several decades.This paper analyzes several actual modeling method on submarine magnetism.The keystone of each method is expatiated and applicability scope is analyzed.At last the choice of methematics models on submarine magnetic field is explained.
