Abstract:The increasing demands for low-cost, compact, and high-resolution radar systems have driven the operation frequency to terahertz (THz) due to the shorter wavelength and larger bandwidth [1]-[5]. However, conventional single-transceiver FMCW radar chips only provide limited signal bandwidth (<; 70GHz [1]-[5]), especially when implemented using CMOS technologies with low fT and fmax. Therefore, prior THz integrated radars are based on compound semiconductors [2]-[4] and have severely degraded performance near the band edges. That not only limits their applications in high-accuracy scenarios like
