RESEARCH Open Access Terahertz active imaging radar

WebbExperimental systems based on THz radar have been proposed over the past decade. In 2008, a 0.58 THz 3D imaging radar system has been successfully developed at Jet Propulsion Laboratory. With a bandwidth of 12.6 GHz, the 0.58 THz radar system obtains the centimeter-scale resolution in 3D scan imaging [3]. WebbThe millimeter wave (MMW) band of frequencies extends from 30 GHz to 300 GHz, with some fuzziness on both ends of this spectrum. The terahertz (THz) band extends from about 200 GHz to about 30 THz, despite the fact that the lower frequencies in this range are not strictly 1012 Hz or higher. dip party sign up sheet
