Research on the Influence From Ocean Environment on the Static Corrosion-Related-electromagnetic Field of a Submarine

The static electric field and magnetic field produced by the corrosion or anticorrosion current of a submarine are new and important target signatures.In order to grasp the rules of the influence on the distribution characteristics of the underwater fields from layered ocean environment,a three-layered conductive media model is adopted to simulate the ocean environment;a static horizontal electric dipole is adopted to simulate the field sources of the corrosion related electromagnetic field,and then the numerical simulation method is used to analyze the influence on the fields from the factors of ocean environment,such as conductivity,seawater depth,and interface.The simulated analysis results show that the layered ocean environment will induce remarkable effect on the field distribution which satisfies general rules.
