Angle of Arrival of Z Echoes

Nature, 1953
IT has been suggested by Scott1 that uncoupled F-region Z echoes are due to longitudinally propagated waves reflected from an area near the magnetic zenith.

Angle of Arrival Localization for Wireless Sensor Networks

2006 3rd Annual IEEE Communications Society on Sensor and Ad Hoc Communications and Networks, 2006
Awareness of the physical location for each node is required by many wireless sensor network applications. The discovery of the position can be realized utilizing range measurements including received signal strength, time of arrival, time difference of arrival and angle of arrival.

Measurement of the Angle of Arrival of Microwaves

Proceedings of the IRE, 1946
This paper describes a method of measuring the direction from which microwaves arrive at a given receiving site. Data which have been collected on two short optical paths using a wavelength of 3¼ centimeters are presented to illustrate the use of the method.

On the dimensionality of spatial fields with restricted angle of arrival

Proceedings. International Symposium on Information Theory, 2005. ISIT 2005., 2005
Wireless communication occurs through continuous fields, over regions of space. Although the communication channel may be modelled in terms of infinite dimensional vector spaces, it is paramount to develop finite dimensional approximations for this channel.

Optimization of Angle-of-Arrival GPS Integrity Monitoring

2015
The paper considers the navigation satellite systems integrity monitoring method which is based on the differences between measured and calculated azimuth and elevation of the navigation signal source respectively. Probability-based integrity monitoring characteristics such as probability of false detection (false alarm probability) and the probability

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.

Tropospheric Effects on Angle-of-Arrival

2013
In 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.

Radar Angle-of-Arrival Estimation

2013
The paper focus on interferometer angle error and on the signal processing required for interferometry, but also introduce monopulse angle-of-arrival for comparison. This chapter, derive the basic equations for monopulse angle estimation and discuss the fundamentals of eigen-based superresolution techniques.
