1. A method of tag tracking/detection, comprising:
receiving, by an antenna of a tag tracking/detection system, a tag signal of a tag in the tag tracking/detection system;
determining, based on a strength or pattern of the tag signal, whether the tag signal only comprises a direct signal that is directly received from the tag or whether the tag signal comprises the direct signal that is directly received from the tag as well as a reflected signal that is reflected by one or more reflective surfaces, wherein the one or more reflective surfaces are configured to focus tag signals of tags in a target location of the tag tracking/detection system toward the antenna of the tag tracking/detection system;
determining, responsive to the tag signal only comprising the direct signal that is directly received from the tag, that the tag is detected outside the target location; and
generating an output signal responsive to the tag signal comprising the direct signal that is directly received from the tag as well as the reflected signal that is reflected by the one or more reflective surfaces, wherein the output signal is indicative of the tag being detected in the target location.
