Abstract: The disclosed FMCW radar system is configured to achieve a wide synthetic bandwidth of operation and a high range resolution. The disclosed FMCW radar system includes a receiver that combines the intermediate frequency (IF) components of multiple narrowband receivers to achieve the millimeter-scale range resolution. The disclosed FMCW radar system can be easily scaled, which enables it to be deployed in large arrays of antennas in order to attain high angular resolution. Additionally, the operation frequency of the disclosed FMCW radar system enables millimeter level cross-range resolution. In this manner, accurate estimation of the location and/or velocity of the objects within the local-sensing range (and potentially beyond) can be achieved.
