Experimental Demonstration of Double-Notch RCS Spectral Signature of Corner Reflector Tag for THz Self-Localization System

Dihedral corner reflectors with arrays of dielectric resonators fixed on the metal plates are shown to exhibit notched spectral signatures of the monostatic Radar Cross Section. Two distinct notches can be created using two arrays with different diameter of resonators. Due to about 45 unique notch combinations, the double-notch corner reflector allows a 5-bit frequency position coding while still producing a sharp pulse shape in time domain. Example designs at V-through G-band are experimentally demonstrated.
