Abstract: Aspects of the present disclosure are directed to radar signaling utilizing a non-uniform multi input/multi output (MIMO) antenna array including first and second uniform MIMO antenna arrays respectively having both sparsely-arranged transmitting antennas and sparsely-arranged receiving antennas. Communication circuitry is configured to determine a direction of arrival of reflections of radar signals transmitted by the transmitting antennas and received by the receiving antennas, by comparing the reflections received by the first MIMO array with the reflections received by the second MIMO array during a common time period (e.g., at the same time). Using this approach, the antenna arrays may be utilized to provide co-prime spacing/elements and to suppress ambiguities in received reflections based on alignment thereof.
