COMPUTER OPTIMIZATION OF A CORNER REFLECTOR FOR ECHO ENHANCEMENT WITH CIRCULAR POLARIZATION

Abstract

When a circularly polarized wave is incident on a trihedral corner reflector, the backscattered wave is circularly polarized with the opposite sense of rotation. However, by coating one of the conducting surfaces of the reflector with dielectric layers, it is possible to obtain a circularly polarized backscatter wave having the same sense of rotation as the incident wave. With the aid of a digital computer, the thicknesses of the dielectric layers can be optimized in an efficient manner to obtain the best performance over the pertinent range of incidence angles. This report includes a computer program for this purpose and describes an optimized four-layer reactive wall.
