Systems and methods for improved angular resolution in multiple-input multiple-output (MIMO) radar

Abstract:

A MIMO radar transceiver assembly includes a plurality of transceiver circuit regions and a plurality of antennas. The plurality of antennas include a first transmit antenna coupled to a first transceiver circuit region among the plurality of transceiver circuit regions, a first receive antenna coupled to the first transceiver circuit region, a second transmit antenna coupled to a second transceiver circuit region among the plurality of transceiver circuit regions, and a second receive antenna coupled to the second transceiver circuit region. At least one of the second transmit antenna and the second receive antenna is interleaved between the first transmit antenna and the first receive antenna. Interleaving of the antennas can increase virtual aperture and angular resolution of the radar system without increasing physical dimensions of the transceiver assembly.
