Recently, powerful, reliable and cost-effective THz radiation photoconductive-emitters have been developed, providing up to 1mW of pulsed power in the range of frequencies between 0.1 and 0.7THz. In this paper we study the potential use of such sources for future pulsed radar systems aiming at stand-off imaging applications. Specifically, we investigate the image frame rate and Signal to Noise Ratio budget that can be obtained using these photoconductive sources. It emerges that adopting a receiving array of 14 times 14 simeq 200 elements, a 3D image with a Field of View (FoV) of 6cm times 6cm times 100cm and resolution of 4mm times 4mm times 1mm can be generated in 80Hz with a SNR { min}= 30dB, including realistic quasi-optical channel efficiencies.
