Patent abstract
A system for geolocating a radio frequency (RF) transmitter in the presence of multipath interference may include a plurality of RF receivers arranged in spaced relation. The system may also include a controller coupled to the plurality of receivers and configured to generate a plurality of measurements associated with the RF transmitter. The controller may also compute a plurality of ambiguity functions based upon the plurality of measurements and due to the multipath interference, and project the plurality of ambiguity functions onto a common geo-referenced grid. The controller may also detect a peak on the common geo-referenced grid indicative of a geolocation of the RF transmitter.
