Angle of Arrival/Direction-Finding Techniques
By CRFS
Angle of Arrival (AoA) or Direction Finding (DF) techniques are perhaps the most widely used ways to geolocate radio frequency signals. In this white paper, we outline the various forms of AoA, including
how they work, how they can be applied in practice, and how they can be combined with other geolocation techniques such as time difference of arrival (TDOA).
