AN APPLICATION OF PRIMARY PTD APPROXIMATION: BACKSCATTERING AT TRIANGULAR CYLINDER
The purpose of the paper is to investigate the backscattering at a triangular cylinder with one soft (electric) face and two hard (magnetic) faces and to reveal the scattering properties of the geometry. In the paper, the backscattered field in the far-zone is introduced using the Physical Theory of Diffraction (PTD), one of the powerful high-frequency approximation techniques. First-order PTD approximation is obtained as a sum of the primary edge waves. Graphical results that have minimums in the radar cross-section represent the importance of geometry in applications of stealth technology. The method used in the paper allows the radar cross section (RCS) to calculate easily using simple trigonometric functions.
