Analysis of RCS characteristic of dihedral corner and triangular trihedral corner reflectors

Method of physical optics is used to simulate backetscattering cross section of dihedral corner and triangular trihedral corner, RCS characteristic of dihedral corner reflectors with a series of parameter changing is analyzed, such as the width, length and intersection angle etc. The reliability of RCS simulation for triangular trihedral corner in this study is verified. The main results and conclusions are as follows: the effects on RCS of dihedral corner reflectors caused by length are slighter than the effects caused by width and intersection angle. The PO is used to compare their RCS.
