Abstract—This Method of physical optics is used to simulate radar cross section characteristic of rectangle triangular trihedral corner reflectors. The reliability of RCS characteristic analysis for rectangle triangular trihedral corner is verified. The experiment and analysis shows that: the rectangle triangular trihedral corner reflector has higher peak values, the further it deviate from the 90°, the peak value dropped, the more obvious; the bottom surface area of rectangle trihedral corner reflector is 1m×1m, side surface area is 1m× 1.5m, elevation angle are 45° and 90°, the RCS value has reached maximum and the RCS curve present symmetrical distribution, and it is one of the most recognizable objects in SAR images.

Index Terms—Rectangle trihedral corner reflector, Radar Cross Section (RCS), physical optics, computer simulation.
