中文摘要：

为了对浅海环境中的船舶轴频电场场源进行建模,以水平时谐电偶极子为基本模拟单元,利用麦克斯韦方程组以及边界条件求解水平时谐电偶极子在空气-海水-海床3层媒质中产生的电场模型。通过实验室船模和海上实船实验的实测数据,证明了水平时谐电偶极子场模型的正确性,表明了船舶轴频电场信号可以用单个水平时谐偶极子作为其等效场源模型,解决了船舶轴频电场场源的建模问题。

英文摘要：

In order to model the ship’s shaft-rate electric field in the shallow sea,a mathematical model of induced electric field associated with horizontal time-harmonic electric dipole which is in air-sea-seabed was proposed based on Maxwell’s equations.The correctness of this model was proved by experiment in the laboratory and in the wild sea.The experimental results prove that the mathematical model of horizontal time-harmonic electric dipole is correct,and the ship’s shaft-rate electric field can be modeled by horizontal time-harmonic electric dipole,which solves the problem of ship’s shaft-rate electric field equivalent source modeling at the same time.
