Robust Navigation Using Angle of Arrival Measurements
ION GNSS+, The International Technical Meeting of the Satellite Division of The Institute of NavigationThe majority of conventional radionavigation systems are based on Time of Arrival (TOA) measurements of RF signals. By far the most common method is pseudoranging, mainly a result of the undisputed success of Global Navigation Satellite Systems (GNSS) as a ubiquitous technology, especially in aviation.

Network localization using angle of arrival
2008 IEEE International Conference on Electro/Information Technology, 2008In this paper, we propose two localization methods using angle of arrival (AoA) information. We assume that nodespsila axis orientations are unknown. Therefore, all AoA measurements are employed to calculate the angle differences of two different nodes viewed by the third one.

A simple technique for angle of arrival measurement
2008 IEEE Antennas and Propagation Society International Symposium, 2008A simple method to calculate the angle of arrival is presented in this paper. The advantages of this method are the unlimited number of the detected angle of arrival in hand and the fact that we donpsilat need to know the nature of the radiating sources in the other hand. However, some disadvantages have been seen.

AnguLoc: Concurrent Angle of Arrival Estimation for Indoor Localization with UWB Radios
International Conference on Distributed Computing in Sensor Systems, 2020The angle of arrival (AoA) estimation is one of the commonly used techniques for indoor localization. Ultrawideband (UWB) radios facilitate AoA estimation through the measurement of the phase difference of arrival (PDoA) at multiple receiver antennas ...

Angle-of-arrival statistics for low resolution antennas
IEEE Transactions on Antennas and Propagation, 2002In a scattering environment, the propagation paths to a receiving antenna arrive from a certain angular spread of directions. For a low-resolution antenna, an apparent direction of arrival may be defined as the azimuth direction of maximum power. A small array is used as the antenna and the spatial derivative of the phase along the array axis is taken ...

The angle of arrival (AOA) is the most valuable piece of information that can be obtained from an enemy radar because the radar cannot change its position drastically in a very short time frame (i.e., a few milliseconds). Unfortunately AOA information is also the most difficult information to obtain. It requires several antennas with receivers. The two

Angle of arrival estimation using spectral interferometry
Journal of Luminescence, 2010We have developed a correlative signal processing concept based on a Mach-Zehnder interferometer and spatial-spectral (S2) materials that enables direct mapping of RF spectral phase as well as power spectral recording. This configuration can be used for precise frequency resolved time delay estimation between signals received by a phased antenna array ...

COMSTAR and CTS angle-of-arrival measurements
Annales des Télécommunications, 1980This brief note describes angle of arrival measurement made at Columbus, Ohio, USA, on 11.7 and 28.56 GHz earth-space paths. These measurements indicate that the short term deviation of the angle of arrival exceeds 0.1° for 0.01 percent of the time. Such a fluctuation would indicate that adverse effects may be expected for receiving apertures having ...

Angle of arrival detection by ESPRIT method
2017 International Conference on Communication and Signal Processing (ICCSP), 2017The direction of arrival estimation of a signal impinging on a array of antennas is an important aspect in signal processing. In order to estimate the angle, we have to relay on a mathematical function known as “pseudospectrum”. This pseudospectrum estimation methods yields best results, when it is employed along with a superior working algorithm to ...
