基于感应磁场的潜艇磁异常计算模型

摘要
由地磁感应引起的潜艇磁异常是现代航空反潜的重要依据,研究磁异常对潜艇防护有重要意义,文中针对潜艇感应磁异常缺乏完整计算模型的现状,采用磁体模拟法将潜艇感应磁矩看作3个正交磁偶极矩的叠加,并根据潜艇椭球体模型在外场中的磁化规律,推导了感应磁矩的解析表达式,进而得到磁异常计算公式。最后通过仿真,得到潜艇感应磁异常在高空的分布特性,仿真结果符合实际情况,基本印证了计算模型的正确性。
The magnetic anomaly of a submarine caused by geomagnetic induction is an important evidence for modern airborne anti-submarine measure. It is of great significance to study the magnetic anomaly for submarine protection. In view of the present situation that there isn't complete calculation model for submarine induced magnetic anomaly, this paper regards the induced magnetic moment of submarine as the superposition of three orthogonal magnetic dipole moments by means of magnet simulation. According to the magnetization law of the ellipsoid model of a submarine in outfield, the magnetic moment expression of a submarine is derived, and then, the computational formula of submarine magnetic anomaly is obtained. Further, the simulation is performed to achieve the induced magnetic anomaly strength distribution of a submarine at high attitude area, and the result conforms to the actual situation, which verifies the correctness of the proposed calculation model.
