This paper proposes a THz linear sparse periodic array (SPA) personnel screening system using multi-pass interferometric synthetic aperture technique. The experimental results have demonstrated that the multi-pass interferometric synthetic aperture imaging can provide an improved image quality on resolution, signal to noise ratio and contrast than the single-pass synthetic aperture imaging.
