Claim 13:
14. A method comprising:
receiving a signal based on a reflection of a transmitted set of chirps;
determining, based on the signal, a set of beat samples associated with the transmitted set of chirps;
performing a range Fast Fourier Transform (FFT) on the set of beat samples to determine a set of range bin values for each chirp of the transmitted set of chirps;
for each group of corresponding range bin values extending across the sets of range bin values:
determining an average value of
adjusting each range bin value in the group based on the average value of the group to produce sets of adjusted range bin values;

determining a direction-of-arrival spectrum for a subset of range bins associated with the sets of adjusted range bin values; and
performing object detection for the signal based on the determined direction-of-arrival spectrum.
