摘要
Abstract
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 mo-ments by means of magnet simulation. According to the magnetization law of the ellipsoid model of a submarine in out-field, 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 cor-rectness of the proposed calculation model.关键词
