Original Abstract Submitted
Technologies described herein relate to a multi-step direction of arrival estimation for imaging radars. A radar system includes X transmitter antennas that output radar signals into an environment and Y receiver antennas that generate detection signals based upon the receiving radar signals output by the transmitter antennas. The system separates the detection signals into N virtual receivers that generate a data cube. The system extracts first values from the data cube that correspond to a first set of virtual receivers and computes a first direction of arrival with respect to a target in the environment based on the first values. The system then computes a second direction of arrival with respect to the target in the environment, that is based upon the first direction of arrival and second values in the data cube that correspond to a second set of virtual receivers.
