摘要

摘要: Salisbury屏具有独特的电磁散射特性，通过巧妙的设计Salisbury屏可以实现雷达目标特征变换的效果。根据Salisbury屏的散射特性，设计了一种新型二面角结构，从理论和仿真角度分析该新型二面角结构的电磁散射特性，分别给出张角为90与60的S屏二面角和金属二面角的雷达散射截面曲线，求解出多种入射角下的正交二面角结构的极化散射矩阵，进一步讨论了雷达工作频率、目标姿态等关键参数对Salisbury屏二面角极化特性的影响。理论分析和仿真结果均表明，与普通金属二面角相比，Salisbury屏二面角的散射特性差异明显，在目标特征变换、电子对抗等领域具有潜在的应用价值。

Abstract: Salisbury screens have a number of unique electromagnetic scattering characteristics.When appropriately designed, the Salisbury screen can reach the radar target signature transform.Based on the electromagnetic scattering characteristics of the Salisbury screen, we designed a novel dihedral corner, and theoretically analyzed and simulated its electromagnetic scattering characteristics in this study.The results reveal the monostatic radar cross section curves of the 90nd 60 Salisbury screen dihedral and metal dihedral, respectively.Taking an orthogonal dihedral corner as an example, we obtained the polarization scattering matrixes for different incident degrees.In addition, we investigated the influence of illumination frequency, target gestures, and other key factors on the polarization characteristics of the Salisbury screen dihedral corner.The theoretical and simulation analysis results show that compared with the conventional metal dihedral corner, the Salisbury screen dihedral corner significantly influences the scattering characteristics and will have potential application in electronic warfare.
