Patent ID: 8723730

Claim:
A system for locating an emitter comprising: a plurality of antennas including a first antenna with a first radiation pattern and a second different antenna with a second radiation pattern different from the first radiation pattern, wherein the first and second radiation patterns provide a received signal gain with respect to signals received from said emitter; a receiver to receive signals from each of said plurality of antennas transmitted by said emitter and obtain received signal strength measurements of said received signals at a plurality of different locations; and a processor to process said received signal strength measurements to locate said emitter, wherein said processor includes: a location module to: process said received signal strength measurements and determine lines-of-bearing to said emitter based on a combination of received signal strength measurements of a signal received by each of said first antenna and said second antenna at said plurality of different locations; and determine a location of said emitter based on intersections of said lines-of-bearing to said emitter at said plurality of different locations.
