Abstract
A method and system for sensorless tracking of an indoor target using a wireless distance measuring technology. A location tracking apparatus is initially moved, and then it is determined whether or not an initial traveling direction of the location tracking apparatus is forward or backward with respect to the target. A minimum distance between the location tracking apparatus and the target during the movement is determined, the minimum distance is stored, and the location tracking apparatus is moved to a location corresponding to the minimum distance, where it is determined whether the location tracking apparatus is directed forward or backward with respect to the target at the location corresponding to the minimum distance. The location tracking apparatus is then moved to the target.
