    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.
