Angle of Arrival/Direction Finding Techniques

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).
