摘要: A system and method for geolocating an RF emitter disposed on or near the ground includes receiving a signal from at each antenna of array N non-collinear antennas, wherein is integer greater than 2; routing received antennas to one bank corresponding receivers; downconverting signals downconverted signals; digitizing digitized channels; using processor determine phase amplitude variations across channels Direction Vector emitter; 2-dimensional pre-determined calibration table look up best match Bearing transforming into locally level reference frame; by determining intersection between frame dataset containing local terrain data.
