## angle of arrival

[′aŋ·gəl əv ə′rīv·əl]
(electromagnetism)
A measure of the direction of propagation of electromagnetic radiation upon arrival at a receiver (the term is most commonly used in radio); it is the angle between the plane of the phase front and some plane of reference, usually the horizontal, at the receiving antenna.

The angle of arrival referenced to the centre point of one sensor pair can be calculated using the inverse cosine function (Arcus-Cosine) (Fig.
The range estimation measurements can be based on different physical variables: received signal strength (RSS), time of arrival (TOA) or angle of arrival (AOA).
Since the perpendicular to the baseline is considered the "zero" angle of an interferometer, angle B is the measured angle of arrival. The angle of arrival at the site also includes the orientation of the baseline.
Delay-line frequency discriminators have long been fundamental components in radar warning receivers, instantaneous frequency measurement receivers (IFM) and angle of arrival interferometers.
By using a hybrid Time Difference of Arrival (TDOA), Angle of Arrival (AOA) technology, and a 30 db improvement in base station location sensitivity, SigmaOne will be able to deliver a system accuracy that exceeds the FCC mandate of 410 feet accuracy (95 percent and beyond), and will allow CDMA carriers to offer a range of location-based services to their customers.
