Abstract:
A radar system includes two or more nodes. Each node includes one or more transmit antennas and one or more receive antennas. The radar system also includes a processor to obtain received signals at each of the two or more nodes, estimate an angle of arrival of each target identified based on the received signals, estimate an offset of each of the two or more nodes from a known location, and compensate for the offsets in the process of estimating the angle of arrival for subsequent targets in the received signals.
