1. An apparatus comprising:
an input to receive radar receive (Rx) data, the radar Rx data based on radar signals received via a radar antenna; and
a processor to generate radar information based on the radar Rx data, wherein the processor is configured to:
determine radar data corresponding to a plurality of range-Doppler bins based on the radar Rx data;
select for a range-Doppler bin of the plurality of range-Doppler bins an Angle of Arrival (AoA) spectrum estimation algorithm from a plurality of AoA spectrum estimation algorithms based on a range value and a Doppler value corresponding to the range-Doppler bin; and
process radar data of the range-Doppler bin according to the AoA spectrum estimation algorithm to generate AoA spectrum information of the range-Doppler bin.
