ABSTRACT:
A system for tracking entities at a work site includes an antenna having a scanned boresight. A controller may be configured to determine a relative angle between a reference associated with the antenna and a source of radiation based on a relationship between boresight orientation and relative power values of a signal received by the antenna from the source of radiation for two or more boresight orientations of the antenna.
