1. A tracking system, comprising:
- an antenna including a scanned boresight; and
a controller 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.

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.

23. A work machine comprising:
-
a body; a first antenna, including a scanned boresight, attached to the body; at least one additional antenna, including a scanned boresight, attached to the body and spaced apart from the first antenna; and a controller, wherein the controller is configured to; determine a relative angle between a reference associated with the first antenna and a source of a radiation based on a relationship between boresight orientation and relative power values of a signal received by the first antenna from the source of radiation for two or more boresight orientations of the first antenna; determine another relative angle between another reference associated with the at least one additional antenna and the source radiation based on a relationship between boresight orientation and relative power values of a signal received by the at least one additional antenna from the source of radiation for two or more boresight orientations of the at least one additional antenna; and determine a range value between the source of radiation and at least one of the antenna and the at least one additional antenna. - View Dependent Claims (24, 25, 26)

30. A tracking system comprising:
-
a first antenna including a scanned boresight; at least one additional antenna including a scanned boresight, the at least one additional antenna being spaced apart from the first antenna; a controller, wherein the controller is configured to; determine a relative angle between a reference associated with the first antenna and a source of a radiation based on a relationship between boresight orientation and relative power values of a signal received by the first antenna from the source of radiation for two or more boresight orientations of the first antenna; determine another relative angle between another reference associated with the at least one additional antenna and the source radiation based on a relationship between boresight orientation and relative power values of a signal received by the at least one additional antenna from the source of radiation for two or more boresight orientations of the at least one additional antenna; and determine a range value between the source of radiation and at least one of the antenna and the at least one additional antenna; and at least one management station in communication with the controller over a network. - View Dependent Claims (31, 32)

33. A method of tracking a source of radiation, comprising:
-
scanning a first antenna having a boresight over a first range of boresight angles; receiving, with the first antenna, a signal transmitted by a source of radiation; monitoring a power level of the signal received by the first antenna over the first range of boresight angles; determining a first boresight angle within the first range of boresight angles that corresponds to a peak in the power level of the signal received by the first antenna; scanning a second antenna having a boresight over a second range of boresight angles; receiving, with the second antenna, the signal transmitted by the source of radiation; monitoring a power level of the signal received by the second antenna over the second range of boresight angles; determining a second boresight angle within the second range of boresight angles that corresponds to a peak in the power level of the signal received by the second antenna; and determining a range value between the source of radiation and at least one of the first antenna and the second antenna. - View Dependent Claims (34, 35, 36, 37)
