Design of a mm-wave MIMO radar demonstrator with an array of FMCW radar chips with on-chip antennas

Single-chip millimeter-wave FMCW radars with on-chip integrated antennas can be used for multi-node radar systems. The design of a MIMO radar demonstrator comprising an array of single-chip radars, each with its own transmitter and receiver and antennas-on-chip, is presented. The system architecture of the demonstrator with the detail of the components needed for the functionality of MIMO radar is explained. For the synchronization between the transmitters and receivers, use of a single reference clock at low-frequency is proposed.
