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 kazimuthal angle θand elevation angle φcombinations associated with each element of the vector, and selecting a selected area in an azimuth-elevation plane around a subset of the kazimuthal angle θand elevation angle φcombinations for each element of the vector. Fine beamforming is performed in the selected area with a second set of kazimuthal angle θand elevation angle φcombinations associated with each element of the vector. The second set of kazimuthal angle θand elevation angle φcombinations is more closely spaced in the azimuth-elevation plane than the first set of kazimuthal angle θand elevation angle φcombinations.
