Abstract :The purpose of the paper is to investigate the backscattering at a triangular cylinder with one soft insert ignore into journalissuearticles values(electric); face and two hard insert ignore into journalissuearticles values(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 insert ignore into journalissuearticles values(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 insert ignore into journalissuearticles values(RCS); to calculate easily using simple trigonometric functions.
