CPC G01S 13/931 (2013.01) [G01S 3/74 (2013.01); G01S 13/426 (2013.01); G06F 18/2431 (2023.01)] | 25 Claims |
1. An apparatus comprising a radar processor, the radar processor comprising:
an input to receive Two Dimensional (2D) radar receive (Rx) data, the 2D radar Rx data based on radar signals of a 2D radar antenna; and
a processor configured to:
determine a first one-dimensional (1D) Angle of Arrival (AoA) spectrum corresponding to a first dimension of an Azimuth-Elevation domain based on a first spectrum analysis of the 2D radar Rx data;
determine a second 1D AoA spectrum corresponding to a second dimension of the Azimuth-Elevation domain based on a second spectrum analysis of the 2D radar Rx data;
detect one or more first object hypotheses in the first dimension based on the first 1D AoA spectrum;
detect one or more second object hypotheses in the second dimension based on the second 1D AoA spectrum;
determine a plurality of 2D object hypotheses corresponding to the Azimuth-Elevation domain based on the first object hypotheses and the second object hypotheses; and
generate 2D AoA information in the Azimuth-Elevation domain based on a 2D AoA spectrum analysis of the 2D radar Rx data according to the plurality of 2D object hypotheses.
