Simulation Analysis of Vertex Triangle Filling Type Abnormal Corner Reflector

In this paper, a vertex triangle filling type abnormal corner reflector is designed. It's filled with a triangle plane parallel to three bevel edges. The designed corner reflector's RCS is calculated and analyzed in detail. The RCS decreases as the filling depth increases, and there is a clear linear positive correlation between the reduction of side area and the equivalent filling depth. The width of the 3dB scattering pattern is larger and RCS fluctuation within the effective azimuth angle is smaller.
