3-D high-resolution imaging at 240 GHz with a single-chip FMCW monostatic radar in SiGe HBT technology

A 3-D high-resolution imaging with a highly-integrated FMCW circularly-polarized monostatic homodyne radar implemented in 0.1μm SiGe HBT technology and operating in the 240GHz transmission window is presented. To address high packaging costs of THz imagers, the radar frontend is realized as a single chip with a silicon lens-integrated on-chip antenna and assembled on a low-cost PCB. The front-end module is further equipped with an external saw-tooth chirp generator and a baseband data acquisition chain to provide the full radar functionality. The complete radar system configured into a simple reflection-mode scanning setup demonstrates a state-of-the-art range resolution of 2.57mm for a 60GHz RF frequency sweep altogether with a 1mm cross-range resolution.
