Abstract
Embodiments include methods, systems and computer readable storage medium for a method for resolving an angle of arrival (AOA) in an antennae array is disclosed. The method includes receiving, from an antenna array of a radar system, antennae data. The method further includes receiving, by the radar system, an iteration counter value. The method further includes calculating, by the radar system, an elevation estimation and an azimuth estimation based on the antennae data and iteration counter value. The method further includes generating, by the radar system, a plurality of hypotheses based on the elevation estimation and azimuth estimation. The method further includes selecting, by the radar system, a hypothesis from the plurality of hypotheses. The method further includes storing, by the radar system, the selected hypothesis.
