Abstract :
Presented is the use of a reflectarray-based structure in order to enhance the radar cross-section (RCS) of a flattened dihedral corner reflector. Phase-shifting cells are printed on the panels of the reflector to steer the reflected beam so that a retrodirective radiation is obtained. An experimental validation is given at 9 GHz.
