摘要
由于纯数学方法计算水下电磁引信物理场特性比较复杂,提出了一种求解水下磁偶极子辐射场和目标散射场的新方法。首先,根据矩量法建立了水下目标电磁散射特性的数学模型,借助FEKO软件建立引信辐射天线与目标舰船的三维模型,并对该模型进行仿真和分析;最后得出引信辐射场和目标铁磁界面散射场的分布特性,以及目标通过特性。仿真结果验证了该方法的有效性。
A method to calculate magnetic-dipole radiation field and target scattering field is proposed because of the complex calculation of physics field characteristics of the underwater electromagnetic fuze by using the traditional method. First, the mathematic model of the electromagnetic scattering characteristics of the underwater target is built based on method of moment （MOM） ,and the 3D model of fuze radiation antenna and target ship is setup by using FEKO software which is then simulated and analyzed. Finally, the distribution characteristics of fuze radiation field and target scattering field and additionally the static passing characteristic of the target ship are obtained. Simulation results show that the proposed method is effective.
