Abstract :
A simple and effective method to reduce the radar cross section (RCS) of a dihedral corner reflector is presented. The RCS of a corner reflector loaded with periodic conducting strips over a dielectric sheet is determined experimentally and is compared with that from the reference target. A typical reduction of 20-30 dB for TE (transverse electric) polarization is shown. The large echo due to the mutual perpendicularity of the two flat surfaces in corner reflector is found to be reduced for TE polarization using the strip grating technique.<>
