An experimental angle of arrival estimation system
[1991] Conference Record of the Twenty-Fifth Asilomar Conference on Signals, Systems & Computers, 2002The authors describe an experimental hardware system used to estimate the angles of arrival of multiple cochannel emitters. The system consists of a four-element phased array antenna and a personal computer housing four coherentized digital receivers.

A New CLEAN Algorithm for Angle of Arrival Denoising
IEEE Antennas and Wireless Propagation Letters, 2009In a previous work, a novel technique for angle of arrival (AOA) measurement was proposed. This technique consists of sweeping the angular domain with one antenna, step by step, such that at each measurement step the received signal voltage at the rotating antenna (sensor) is measured.

Tropospheric Effects on Angle-of-Arrival
2013In this chapter, we characterize the effects of angle bias due to refraction and angle precision due to turbulence. As a result, angle bias due to refraction can be calibrated and removed, if possible, and any residual error can be quantified in the interferometer angle error budget.

WLAN Indoor Localization Using Angle of Arrival
2018With the development of information technology and the rising of demanding for location-based services, indoor localization has obtained great attentions. Accurate estimation of Angle of Arrival (AoA) of signals make it possible to achieve a high precision location. So as to resolve multipath signals effectively and then extract AoA of the direct path,

Angle of arrival of ten centimeter microwaves
2012The path of an electromagentic wave propagated through the earth's atmosphere depends upon the homogeneity of the atmosphere. For the well mixed condition, which is the case most of the time, the wave follows a straight or a smoothly curved path. However, if the atmosphere is not homogeneous, the wave may change direction abruptly along the path. It is

Angle of Arrival Calculations at 10.6 microns
1971Abstract : The report deals with the specification of the angular position of objects by measurement of the angles of arrival of light beams; and with the measurement uncertainties due to atmospheric turbulence. A survey of the literature is presented showing two approaches to angle of arrival, one for large aperture receivers and one for a single ...
