Paper Abstract

Based on the measurement results of a 5 GHz CMOS radar microchip, it is shown that low power CMOS radar-on-chip integration can have high detection sensitivity despite the large flicker noise and phase noise contributions around the signal of interest. Key technologies to further increase the detection sensitivity will be discussed, including software configured DC offset calibration, noise suppression using tunable baseband bandwidth limiter, and special receiver architecture for flicker noise reduction. The applications of low-cost high-sensitivity on-chip radar will be focused on surveillance and reconnaissance, sensing through-wall radar, ground penetration radar, border monitoring, and moving target detection.
