All-Electronic Terahertz 3-D Imaging System Based on FMCW

This paper presents an all-electronic Terahertz (THz) 3-D sub-millimeter imaging system based on frequency modulated continuous wave (FMCW), whose frequency ranges from 340GHz to 500GHz. For high-resolution cross-range imaging, the focused method is used instead of the traditional synthetic aperture technique. The imaging performance of the system is verified by some experimental results.
