This paper describes a phase-modulated Continuous-Wave (CW) Radar TX that operates in the 79GHz band. With a sampling rate of 2GS/s and 4GHz RF bandwidth, we target a resolution of 7cm. We rely on a Pseudo-Random-Noise (PRN) maximum length sequence of 511 bits and BPSK modulation targeting three benefits. First, SNR is increased by 27dB thanks to compression gain. Second, a code-domain MIMO radar is now possible yielding both higher angular resolution for a given number of antenna elements and higher combined output power than a similar time-domain MIMO radar. Finally, interference rejection techniques can be applied in the digital domain. Such radar architecture is digital intensive so that a CMOS technology allows for a more power-efficient implementation compared to equivalent SiGe state-of-the-art [7-8]. This paper proposes the first 79GHz radar TX in 28nm CMOS. |
