| Popis: | This paper presents digital techniques to improve performance parameters of an mm-wave Frequency Modulated Continuous Wave (FMCW) radar front end. It proposes calibration techniques to: a) reduce a complex (IQ) baseband receiver’s (RX) quadrature mismatch (IQMM) and a beamforming transmitter’s (TX) phase shifter inaccuracies, b) reduce RX analog baseband mismatches, and c) reduce effect of multiplicative noise arising from strong TX-RX external coupling / reflections from radar-casing. Benefits are demonstrated with measurements from a 45nm CMOS 77GHz band radar SoC. |
