Abstract: Embodiments include methods, systems and computer readable storage medium for a method for determining a fine direction of arrival (DOA) for a target is disclosed. The method includes receiving, by a plurality of receivers of a radar system, radar signals reflected by a target. The method further includes mitigating, by the radar system, phase shifts in the radar signals caused by a motion of the target. The method further includes determining, by the radar system, the fine DOA in response to the mitigation of phase shifts and based on the radar signals. The method further includes estimating and storing, by the radar system, a Doppler frequency based on the fine DOA.

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.

Abstract: A vehicle, vehicular system and a method of detecting an object. The vehicular system includes a multi-input multi-output (MIMO) radar array and a processor. The MIMO radar array is configured to obtain a radar signal from the object. The processor is configured to determine a differential phase of the radar signal for the MIMO array, generate a probability map from a sign of the differential phase, and confirm the detection of the object
