Comparison of two angle of arrival averaging strategies

2009 Canadian Conference on Electrical and Computer Engineering, 2009
The accuracy of direction finding (DF) systems can often be improved by using techniques for the time averaging of information from multiple data records, particularly when the signal-to-noise ratio is low. In certain DF systems, the emitter angle of arrival (AOA) is computed from the phase angle of a complex-valued signal. For this type of DF systems,

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.

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.
