In order to improve the magnetic defense of the ship and reflect ship magnetic field exactly, the ship magnetic field measuring needs advanced magnetic measure technique. In this paper, the magnetic dipole array is used to simulate the ship magnetic source. The paper gives a mathematical model of ship magnetic field conversion is built up according to the real magnetic field data on the surface of the ship fathom. A mathematical model for magnetic conversion after magnetic measuring that combines the dot matrix Large-scale Area method and the magnetic charges arithmetic is established in the example. The mathematical principle, calculation methods of magnetic function and parameters decision of the model are discussed. The simulation results demonstrate that the model is of high precision. Application of magnetic measure technique on magnetic defense is of important practical reference.
