A silicon photonics millimeter-wave (mm-wave) radar receiver (RX) integrated circuit (IC) for a multiple-input-multiple-output (MIMO) imaging radar is presented. Optical clock distributed over fiber enables coherent operation of several transceiver frontends for large apertures and finer angular res...
