WebDoppler radio direction finding, or Doppler DF for short, is a radio direction finding method that generates accurate bearing information with a minimum of electronics. It is best suited to VHF and UHF frequencies, and takes only a short time to indicate a direction. http://beyourfinest.com/radio-detection-finding-rdf/
