Analysis of Electromagnetic Scattering Characteristics of Terahertz low-frequency Paraboloid Antenna

针对目标电磁散射特性,本文从抛物面天线着手进行分析,对目标的几何形状进行建模,然后采用高频近似电磁计算方法对目标进行多角度、多频点、全极化的单站散射场进行计算,从而更加快捷准确得到结果。在目标散射特性计算中,本文提供了一种更好的基于SBR方法的渐近求解器完成本文的电磁散射特性计算,并在仿真中验证了新方法的有效性。

According to the electromagnetic scattering characteristics of target, this article from the parabolic antenna are analyzed, the target geometry modeling, and then use the high-frequency approximate calculation method of electromagnetic multi angle, the target of multi frequency point, ful polarization single station scattering field is calculated, thus more accelerate the fast and accurate results. In the calculation of target scattering characteristics, this paper provides the calculation of electromagnetic scattering properties of a better asymptotic solver based on SBR method in this text, and verify the effectiveness of the new method in the simulation.
