Claim 6:
7. A system comprising:
receiving circuitry to couple to a plurality of antennas and configured to:
receive a radar signal based on a reflection of transmitted set of chirps, and
determine a series of beat samples of the radar signal for each antenna of the plurality of antennas based on the transmitted set of chirps; and

a signal processor coupled to the receiver and configured to:
perform a range Fast Fourier Transform (FFT) on each series of beat samples to determine an array of range bin values for each chirp of the transmitted set of chirps to determine a set of arrays of range bin values for each antenna of the plurality of antennas;
produce sets of arrays of adjusted range bin values for each antenna of the plurality of antennas based on the series of beat samples;
determine a direction-of-arrival spectrum for a subset of range bins associated with the plurality of sets of arrays of adjusted range bin values; and
perform object detection for the radar signal based on the direction-of-arrival spectrum of the subset of range bins.
