Abstract
A discrete three-dimensional receiving element has multiple sensors scattered over its surface to detect and locate a signal. The sensors facing the signal detect the signal, and a boundary line is drawn between the sensor which detect the signal and those which don't. The strength of signal may also be detected. A plane is drawn through the receiver element, and the direction of the signal is determined as generally perpendicular to the plane, in the direction of the sensors which are receiving the signal. Distance to the source may also be determined based on signal strength. The location of the signal source may be transmitted to a remote location, or the receiver may direct an electromagnetic beam toward the source to detect further information about the source.
