摘要
针对现行水中航行器尾流的感应电磁场模型的建立,所存在的水下有限深度航行器尾流感应电磁场研究甚少、分析不足的问题,文中在深入分析理论知识与研究水下航行器产生尾流的基础上,根据麦克斯韦方程组推导出水下航行器尾流的空气-海水-海底3层浅海感应电磁场模型。采用高斯积分法对其进行求解,并分析电磁场的传播、频率等特性。最后通过实例仿真证明了,所建感应电磁场模型具有传播距离远、持续时间长与频率低的优点,对未来水下航行器的探测研究与发展提供了重要依据与思路。
In view of the establishment of the induced electromagnetic field model of the underwater vehicle wake,the research on the electromagnetic field of the tail water of the underwater limited depth vehicle is very little and the analysis is insufficient.On the basis of deep analysis of theoretical knowledge and research on the wake produced by underwater vehicle,according to the Maxwell equations wake-air-sea seabed three shallow water induction electromagnetic field model for wake of under water vehicle is derived,then it was solved by using Gauss integral method,and this paper analyzes electromagnetic field propagation and frequency characteristics.Finally,the result of simulation proves that the proposed model has the advantages of electromagnetic field propagation distance,long duration and low frequency,provides an important basis and ideas for the future of underwater vehicle detection research and development.
