Abstract
A multiple-input-multiple-output (MIMO) radar system comprises two or more software-defined millimeter-wave (SDMMW) nodes, a host processing system that is electrically coupled to the two or more SDMMW nodes, and a MIMO aperture array coupled to the two or more SDMMW nodes. The MIMO radar system is configured to form a MIMO TX channel and a MIMO RX channel for each of the two or more SDMMW nodes. The MIMO radar system includes a millimeter wave (MMW) frequency-modulated continuous wave (FMCW) oscillator source configured to generate a MMW FMCW signal. For each of the two or more SDMMW nodes, the radar system includes an upconverter assembly and a downconverter assembly.
