摘要

潜艇的腐蚀和耐腐蚀电流在海水中经过螺旋桨旋转调制后会产生极低频电场。它成为信号源最重要的特性之一。利用电赫兹矢量导出了海水中电偶极子的电场和磁场表达式，并给出了标准场的表达式。测量和数值模拟表明，潜艇的标准场幅值在轴频处处于较大位置。并且轴速电场可以远距离接收。因此，利用轴速电场进行潜艇探测可能是最好的方法。

Effect of seawater on radiation field of electric dipole

The corrosion and corrosion resistance current of the submarine will produce extremely low frequency electric field after modulated by the propeller rotation in the seawater. It becomes one of the most important characteristics of the signal source. We derive the expression for the electric and magnetic fields of the electric dipole in the seawater using the electric Hertz vector, also give the expressions for the standard field. Measurements and numerical simulations show that the standard field amplitude of the submarine in the shaft frequency is in a great location. And the shaft - rate electric field can be received in a long distance. Therefore, submarine detection using the shaft - rate electric field can be probably best carried out.
