Scattering characteristics computation method for corner reflectors in arbitrary illumination conditions

Abstract

The calculation method for obtaining scattering characteristics of corner reflectors is proposed. The method allows calculating the radar cross-section of corner reflectors for arbitrary aspect angles. The method proposes separating the smooth part of reflectors and some neighborhood of their edges (including that of inner edges). The method accounts for multiple reflections between smooth parts of the reflector surface. In addition, the reflector surface can have a radar absorbing or dielectric coating. The proposed method is used for radar cross-section calculation of trihedral and dihedral corner reflectors.
