Abstract:
A method for use in collecting information about a plurality of emitters, said method comprising the steps of:receiving electromagnetic pulses from a plurality of remote emitters at a first location;measuring, for each of said electromagnetic pulses, a relative position of a corresponding emitter with respect to said first location;sorting said electromagnetic pulses into a plurality of groups based on measured relative position information, each of said plurality of groups corresponding to a particular emitter within said plurality of remote emitters;analyzing electromagnetic pulses within each of said plurality of groups to identify a group corresponding to an emitter having a predetermined transmission characteristic; andtransmitting data about the identified group to a remote processing station via a communication link between said first location and said remote processing station, wherein said remote processing station is operative for analyzing said data to derive additional information about the corresponding emitter.
