| 摘 要： | 舰船轴频电磁（EM）场可应用于新型鱼水雷武器引信,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.本文通过运动垂直时谐偶极子在浅海环境下产生的电磁场的研究分析了不同影响因素对舰船轴频电磁场的影响.运用基于汉克尔变换式的FFT变换算法对偶极子所得到的电磁场解析式进行了数值模拟,模拟得到了不同影响因素下舰船轴频电磁场的仿真结果.

| Abstract: | 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）. This paper analyzes the different factors about EM field of ship. Based on the Hankel equation, using the FFT transfer algorithm to calculate analytic expression of EM field, by simulation, we can get the effect of different factors about shaft frequency EM field by simulation. |
