A High-Resolution Terahertz LFMCW Experimental Radar

Conference paper
Part of the Lecture Notes in Electrical Engineering book series (LNEE, volume 246)


A summary of UESTC’s Terahertz (THz) imaging radar is presented, with an emphasis on some key design aspects. By using of the linear frequency modulated continuous-wave (LFMCW) radar technique with a 4.8 GHz bandwidth, nearly 3 cm range resolution is achieved. Some measures are taken for correcting the signal error in the intermediate frequency receiver to optimize the radar’s range resolution. High dynamic range detection comes from the radar’s system structure, low-noise LMF source. And the radar image can be acquired in ISAR imaging mode.
