舰船磁场模型适用范围研究

Research on the Applicability of Warship Magnetic Model

目前用于探测定位的舰船磁场模型中应用最为广泛的是磁偶极子模型,但是对于磁偶极子模型的适用观测距离缺乏定量研究。文章利用椭球体模型近似表达实际磁场,通过椭球体模型与磁偶极子模型的仿真比较,对磁偶极子模型的适用观测距离进行定量研究,得出磁偶极子模型的适用条件。

At present in warship magnetic models, the magnetic dipole model is used widely, but there is few quantitative study about the applicability of magnetic dipole model is lack. The ellipsoid model was used to express the actual magnetic approximately, and the ellipsoid model and the magnetic dipole model were emulated and compared, and the quantitative study about the applicable
