A method for locating a target wireless device is disclosed. At least one directional antenna is swept through a field of view at each of a plurality of sensing locations. A position is determined for each of the plurality of sensing locations. During the sweep at each of the plurality of sensing locations, a set of signal strength data for the target wireless device and a set of bearing information are collected. A plurality of lines of bearing are determined, one from each of the plurality of sensing locations to the target wireless device, based on the determined position, the collected set of signal strength data, and bearing information for each of the plurality of sensing locations. A target location of the target wireless device is determined based on an intersection of at least two lines of bearing from the plurality of lines of bearing.
