This work presents a new radar system concept, working at millimeter wave frequencies, capable of detecting explosive related threats at standoff distances. The system consists of a two dimensional aperture of randomly distributed transmitting/receiving antenna elements, and a Passive Array of Scatters (PAS) positioned in the vicinity of the target. In addition, a novel norm one minimization imaging algorithm has been implemented that is capable of producing super-resolution images. This paper also includes a numerical example in which 7.5 mm resolution is achieved at the standoff range of 40 m for a working frequency of 60 GHz.
