We have developed a 3-D high-resolution radar at 300 GHz with a cell resolution of 1 x 1.6 x 1.6 cm(3) at a standoff distance of 8 m for security applications. The selection of an operating frequency of 300 GHz, a bandwidth of 27 GHz, and a field of view of 50 x 90 cm(2) improves the through-clothes imaging of person-borne concealed objects. The radar's antenna design allows single-pixel imaging at a frame rate of two frames per second. A reduction in cost and power consumption and improvements in image quality are additional requirements taken into account in the design of this radar system.
