Millimeter (MM) and Terahertz (THz) waves are transparent to many non-metallic materials and is expected to be applicable for non-destructive inspections. Especially, the radar 3D imaging technique using the semiconductor continuous wave (CW) sources is important because of its compactness, stability and high signal-to-noise ratio (SNR). In this presentation, we will introduce the development of the prototype system of a 300 GHz walk-through body scanner for the security gates of public transportation. In the system, we utilize the frequency-modulated continuous wave (FMCW) method to realize the 3D imaging of a material hidden under cloths. In this presentation, we will present the configuration and the actual imaging results.
