Claim Text:
1. A radar system suitable for an automated vehicle, said system comprising: a plurality of antennas configured to detect a reflected radar signal reflected by an object in a field-of-view of the system, wherein each antenna of the plurality of antennas is configured to output detected signals indicative of the reflected radar signal detected by each of the plurality of antennas; and a controller configured to receive the detected signals from the plurality of antennas, determine if the object is present in the field-of-view based on the detected signals, determine a phase-difference between symmetrical-frequency-bins for each antenna, wherein the symmetrical-frequency-bins are symmetrically offset from a maximum-amplitude non-coherent-integration detection-frequency-bin (max-NCI-bin), and determine a classification of the object based on a time-domain-analysis of the phase differences across the plurality of antennas.
