1. An electronic device, comprising:
a processor configured to:
obtain signal information based on wireless signals received from an external electronic device via a first antenna pair and a second antenna pair, wherein the first and second antenna pairs are aligned along different axes and wherein the signal information includes channel information, range information, a first angle of arrival (AoA) of the wireless signals based on the first antenna pair, and a second AoA of the wireless signals based on the second antenna pair;
generate an initial prediction of a presence of the external electronic device relative to a field of view (FoV) of the electronic device based on temporal patterns of the signal information, wherein the initial prediction includes an indication of whether the external electronic device is within the FoV or outside the FoV of the electronic device;
perform, using a tracking filter, a smoothing operation on the range information and the first and second AoA, the smoothing operation generating a predicted location of the external electronic device relative to the FoV of the electronic device; and
generate, based on the smoothing operation, confidence values associated with the predicted location.
