N2 - A sub-mm system prototype is presented for imaging objects hidden under human body clothes. The system is primarily intended for in-door and out-doors homeland security applications. Its hardware is based on Rx-Tx modules operating with FMCW signal at the range 325 - 335 GHz. In order to improve spatial resolution the standard horn antennas have been integrated with focusing Teflon lenses. Computer design of such antenna system has been performed using CST Microwave Studio I-Solver. As a result the beam spot diameter about 1cm at the distance up to 2m was formed. The target imaging algorithms based on averaged-weighted procedure has been suggested for reconstructing the shape of a tested object. Examples of 2D and 3D image reconstructions are reported.
