摘要
为实现舰船静态电场的深度换算,给出了空气—海水—海床3层模型中电偶极子在海水中产生的电场强度解析式,并进行了数值仿真;基于电偶极子模型对舰船静态电场进行了建模,根据以往的舰船电场换算实例进行了验证.实验结果表明:可由水下标准测量面电场强度实时换算得到较大深度的电场各分量;实测数据与仿真结果两者吻合较好,显示了舰船静态电场深度换算方法的有效性.该模型需要的参数少、计算量小,能够实现电场的实时换算.
To realize the conversion of the static electric field depth,the analytic expression of electric field intensity in the sea water was given,based on electric dipole in the three layer model of air-sea water-sea bed,and the corresponding numerical simulation was done.On the basis of the dipole model,the static electric field was modeled,and the model verified in terms of the conventional conversion examples of ships’static electric field.The experimental results show that the electric field intensity measured on the standard plane of measurement below water can be converted to obtain the various electric field components at deeper water in real time.The measured data coincide with the simulation results better,showing the effectiveness of ships’static electric field depth conversion.The parameters required by the model are fewer and the computation is less,thus realizing the real time conversion of the electric field.
