1. A method comprising:
obtaining signal information based on wireless signals communicated between an electronic device and a target device, the signal information including channel information, range information, and angle of arrival (AoA) information;
obtaining motion information based on movement of the electronic device, the motion information including orientation of the electronic device;
identifying first location information based on the motion information and the channel information, the first location information indicating whether the target device is within a field of view (FoV) of the electronic device;
identifying second location information based on the orientation of the electronic device and the AoA information, the second location information indicating whether the target device is within the FoV of the electronic device;
determining whether the electronic device is in motion based on rotary motion; and
determining whether the target device is within the FoV or outside the FoV of the electronic device based in part on the first location information in response to determining that the electronic device is not in motion or the second location information in response to determining that the electronic device is in motion,
wherein identifying the second location information comprises:
in response to determining that the electronic device is in motion, determining, based on an AoA indicated in the AoA information, whether the target device is within a threshold range of angles extending from a boresight direction of the electronic device;
in response to determining that the target device is within the threshold range of angles, identifying a correlation value between the AoA and the orientation for a current timestamp;
comparing the correlation value to a correlation threshold; and
updating a memory with the correlation value based on the comparison.
