可探测舰艇电磁特征的水雷传感器目前正在研制,故水面舰艇和潜艇的电磁特征又重新引起了人们的关注。电磁特征主要有3种:静电特征,即水下电位(UEP);与腐蚀有关的磁特征;极低频电磁特征。电磁特征的产生舰艇每种特征主要由艇体周围水中形成的电流产生。它们是通过艇体腐蚀而诱发的电化学反应和使用外加电流阴极保护系统形成的。直流腐蚀电流是在艇体腐蚀过程中产生电流的结果。潜艇如不采用外加电流阳极保护
The mine sensors that can detect the electromagnetic characteristics of naval vessels are currently being developed, so the electromagnetic characteristics of surface ships and submarines have again attracted people's attention. Electromagnetic characteristics are mainly three kinds: electrostatic characteristics, namely underwater potential (UEP); and corrosion-related magnetic characteristics; very low frequency electromagnetic characteristics. The generation of electromagnetic characteristics Each characteristic of the ship is mainly generated by the current formed in the water around the hull. They are formed by the electrochemical reaction induced by hull corrosion and using an impressed current cathodic protection system. DC corrosion current is the result of current generation during corrosion of the hull. Submarines, such as not using anodic current protection
