Abstract
A relative positioning system and method has an adjoining pair of spaced apart receivers positioned proximal to an object causing a signal interference with a radio frequency signal detectable by each receiver of the adjoining pair. The radio frequency signal is associated with an emitter. Control electronics operatively couple the spaced apart receivers. The control electronics are configured to determine a direction of the emitter based on the signal interference. In an embodiment of the system and method the emitter is associated with an object of interest, the signal encodes information relating to the identity and status of the object, and information and heading of the object are cutaneously communicated to an operator by an article worn by the operator.
