  • Resolving doppler ambiguity in multi-input multi-output radar using digital multiple pulse repetition frequencies
    Patent number: 11119185
    Abstract: A system and method to detect a target with a radar system of a vehicle involve transmitting two or more chirps, in turn, from two or more transmit elements. Each chirp is a continuous wave liner frequency modulated waveform. The method also includes receiving reflections generated by each of the two or more chirps from each of the two or more transmit elements at two or more receive elements, and processing the reflections based on a Doppler sampling frequency corresponding with a period of each of the two or more chirps to determine velocity of each detected target relative to the vehicle.

  • Two-stage beamforming
    Patent number: 10571557
    Abstract: A system and method to perform two-stage beamforming in a radar system includes obtaining an incoming signal vector x associated with a detected target. The method also includes performing coarse beamforming with a first set of k1 azimuthal angle ?i and elevation angle ?i combinations associated with each element of the vector, and selecting a selected area in an azimuth-elevation plane around a subset of the k1 azimuthal angle ?i and elevation angle ?i combinations for each element of the vector. Fine beamforming is performed in the selected area with a second set of k2 azimuthal angle ?i and elevation angle ?i combinations associated with each element of the vector. The second set of k2 azimuthal angle ?i and elevation angle ?i combinations is more closely spaced in the azimuth-elevation plane than the first set of k1 azimuthal angle ?i and elevation angle ?i combinations.
