为了利用舰船腐蚀静电场对舰船实现跟踪和定位，需要了解舰船腐蚀静电场在海水中的传播规律。采用三维边界元法建立潜艇腐蚀静电场模型，研究海水中水平方向、深度方向和斜45°方向上传播距离对舰船静电场的影响，分析静电场Ex，Ey和Ez分量在水下20 m处水平方向的分布规律和其在3个方向上的水下传播规律。仿真结果表明：在水下20 m处水平方向上Ex和Ez关于垂直面对称分布，Ey关于垂直面反对称分布；在3个方向上静电场分量随着距离的增加不断减小，Ex在3个方向上信号强度最大，可作为舰船定位和水中武器的目标信号。
In order to use the corrosion electrostatic field of ship to track and locate the ship, it is necessary to understand the propagation law of corrosion electrostatic field of ship in seawater. A three-dimensional boundary element method was used to establish a submarine corrosion electrostatic field model, and the influence of the propagation distance in the horizontal direction, the depth direction and the oblique 45° direction in the seawater on the electrostatic field of the ship was studied, and the components of Ex, Ey and Ez of the electrostatic field in the water were analyzed. The distribution law in the horizontal direction at the bottom 20 m and its underwater propagation law in three directions. The simulation results show that Ex and Ez were distributed symmetrically about the vertical plane in the horizontal direction at 20 m underwater, and Ey was distributed antisymmetrically about the vertical plane; the electrostatic field component decreases with the increase of distance. Ex is the highest in three directions, and can be used as the target signal for ship positioning and underwater weapons.
