  • Gain projection geo-location systems and methods
    Patent number: 9176218
    Abstract: A system and method for estimating the geographic location of an RF emitter which involves spatially filtering and receiving RF signals through use of a beamforming antenna array having multiple overlapping beams; detecting and measuring the time-of-arrival and amplitude of signals which are received in each beam through use of multiple synchronized receivers; identifying simultaneous detections of the same emitter which have occurred in adjacent beams; projecting the associated beamformed antenna gain patterns onto the underlying terrain for all instances in which there was a simultaneous detection in adjacent beams; weighting and accumulating all projections to form a Maximum Likelihood Surface (MLS); and finally, estimating the location of the emitter through analysis of the resulting MLS.
    Type: Grant
