舰船轴频电磁( EM)场可应用于新型鱼雷武器引信，运动舰船轴频电磁场建模可通过运动的垂直时谐偶极子实现。本文根据单个运动垂直时谐电偶在海水中固定场点产生的电磁场公式，采用基于汉克尔变换的快速FFT算法得到t时刻在固定场点产生的电磁场，通过推导得到4个运动垂直时谐电偶极子在固定场点产生的电磁场公式。通过推导的公式对四桨运动舰船的轴频电磁场实现仿真。

EM field can be used to fuze the neotype torpedo, the shaft frequency EM field can be modeled by moving time harmonic moving vertical electric dipole ( VED ) . According to the equations of electromagnetic ( EM ) field of single propeller of moving time-harmonic dipole. Based on the Hankel equation, using the FFT transfer algorthm to calculate the EM field at fixed point. Finally we obtain the EM equation of four time-harmonic dipole at fixed point. Through the equation, the shaft-frequency EM field of four propeller moving ship has been modeled.
