Abstract :
We present the hardware and the experimental results from a 600 GHz imaging radar with sub-centimeter resolution in all three spatial dimensions. The FMCW radar transceiver is built on a back-end of commercial microwave components - with a front-end of custom designed frequency multipliers and mixers. The optics consists of a 40 cm diameter ellipsoidal primary reflector with a 4 m focal length. The acquired images will be compared with those achieved with a more traditional sub-millimeter wave active imaging technique.
