This study investigates the characteristics of electromagnetic scattering in complex electromagnetic environments by using half-space theory with multiple radiators. We identify differences in the characteristics of the target scatterings between single and multiple radiators of a radar in the half-space through a comparison between the half-space and free space and single and multiple radiators. Numerical examples featuring a prismatic model of the perfect electronic conductor and the cruise missile model are used to show that the distribution of surface current density is affected by both the half-space and multiple radiators. The variation in surface current density changes the characteristics of scattering, and such a condition is reflected in the patterns of radiation. To further examine the influence of this phenomenon on multiple radiators, factors such as the amplitude of the electric field, phase difference, and mode of polarization were considered. The results show that the characteristics of scattering are significantly influenced by a number of factors.

多个辐射体的半空间电磁散射特性

本研究通过使用带有多个辐射体的半空间理论研究复杂电磁环境中的电磁散射特性。通过比较半空间和自由空间与单个和多个辐射器之间的比较，我们确定了雷达在半空间中的单个和多个辐射器之间的目标散射特性的差异。数值示例以完美的电子导体的棱柱模型和巡航导弹模型为例，用于表明表面电流密度的分布受半空间辐射器和多个辐射器的影响。表面电流密度的变化改变了散射的特性，并且这种状态反映在辐射的图案中。为了进一步研究此现象对多个散热器的影响，考虑了诸如电场幅度，相位差和极化模式之类的因素。结果表明，散射的特性受到许多因素的显着影响。
