浅海中非金属圆柱体的扰动电场

Disturbed electric field of nonmetallic cylinders in shallow sea

为研究主动电场作用下非金属圆柱体目标所产生的扰动电场分布,基于镜像法和区域网格化的思想,建立了浅海环境下非金属目标的二次电偶极子模型。利用该模型计算出目标周围不同位置处的扰动电场,并与边界元软件仿真结果进行对比,结果表明扰动电场水平分量误差小于3%。开展水池模型实验,实测结果与所提模型计算值基本一致,证明了所建立的二次电偶极子模型的准确性。

In order to study the distribution of disturbed electric field produced by a non-metallic cylindrical target under active electric field,the second electric dipole model of a non-metallic target in shallow water environment was established on the basis of the mirror method and the regional gridding method.By using the established model,the disturbed electric field at different positions near the target was calculated and was compared with the simulation results of boundary element method software.The results show that the error of the horizontal component of the disturbed electric field is less than 3%.Then an experiment was carried out in a water tank.The result data from test were basically consistent with the calculated results,which shows that the established secondary electric dipole model is accurate.
