Abstract

In this article, a 60-GHz frequency-modulated continuous-wave (FMCW) multiple-input multiple-output (MIMO) radar system using frequency-division multiplexing for TX signal separation is presented. Four-channel transmitter and receiver chips were designed using 130 nm SiGe process. The total number of TX and RX channels can be scaled by the number of chips in the system while still maintaining phase coherence between the channels. 2-D and 3-D object localization measurements are made with four TX and eight RX channel systems. In the 2-D configuration, the radar system is capable of a 5-cm range resolution and 3.5° angular resolution.
