为研究倾斜海床环境舰船电场的分布,首先通过构建空气-海水-斜坡海床三层介质模型,采用镜像法推导了位于海水中的水平电偶极子在全空间产生的场分布,验证所得标量电位表达式满足边界条件;然后,分析了斜坡海床条件下舰船静电场的分布规律,并进行了数值仿真和实验验证.结果表明:实测数据与仿真分析相符合,电位分布表现出明显的通过特性,且达到可探测的量值.
A three-layer of air-seawater-inclined seabed model is proposed to study the distribution of static electric field of ship under the condition of inclined seabed.The electric field distribution of hori-zontal static electric dipole in the seawater is deduced by using mirror image theory.The analytical ex-pression of scalar potential obtained from the study satisfies the boundary conditions,which proves the validity of deduced results.In addition,the numerical simulation and experimental measurement of electric field distribution in the seawater are made.The results show that the actual observed record is in agreement with the simulation analysis which shows distinct through characteristic,and the elec-tric potential reaches a detectable magnitude,which gives a new insight into target detection in the water.
