RF angle of arrival-based node localisation

International Journal of Sensor Networks, 2011
Several localisation algorithms exist for wireless sensor networks that use angle of arrival measurements to derive node position. However, there are limited options for actually obtaining the angle of arrival using resource-constrained devices. In this paper, we describe a technique for determining node bearings based on radio interferometric angle of

Angle-of-arrival statistics for low resolution antennas

IEEE Transactions on Antennas and Propagation, 2002
In 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 ...

Robust Navigation Using Angle of Arrival Measurements

ION GNSS+, The International Technical Meeting of the Satellite Division of The Institute of Navigation
The 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.

Improved Angle-of-Arrival Estimation of Narrow Gaussian Beams for Mobile FSO Platforms

IEEE Transactions on Aerospace and Electronic Systems
Due to the narrow beamwidths of laser Gaussian beams, accurate tracking of laser beam’s angle-of-arrival is an important problem in mobile free-space optical communications.
