An electro-optic measurement system for electric fields near RF and microwave radiators and scatterers
(Stellenbosch : Stellenbosch University, 2000-12)
ENGLISH ABSTRACT: An electro-optic sensor system was developed which uses the modulated scatterer technique  to measure the fine structure-amplitude and phase-of electric fields with the minimum of perturbation. The ...
Evaluation of selected subspace tracking algorithms for direction finding
(Stellenbosch : University of Stellenbosch, 2007-03)
This thesis examines three reduced complexity algorithms for subspace tracking in the context of radio direction finding. Projection Approximation Subspace Tracking (Yang), the Fast Data Projection Method (Doukopoulos ...
Investigation of the scanning performance and enhancement of an electrically large array
(Stellenbosch : University of Stellenbosch, 2008-03)
An existing antenna used in satellite communications is investigated with the goal of improving low angle radiation performance and reducing manufacturing costs. To understand this antenna it is modelled, simulated and ...
