• Calibration of large Rogowski coils 

      Combrink, Stephanus Lucas (Stellenbosch : Stellenbosch University, 2016-03)
      ENGLISH ABSTRACT: The Square Kilometre Array aims to be the world’s largest radio telescope. South Africa will host the mid to high frequency division of the SKA and the core site will be populated with 64 offset Gregorian ...
    • Development of a real-time transient analyser for the SKA 

      Botha, Antheun (Stellenbosch : Stellenbosch University, 2014-04)
      ENGLISH ABSTRACT: The extension of the Karoo Array Telescope (KAT), MeerKAT, will be the most sensitive radio telescope in the southern hemisphere until it is superseded by the completion of the Square Kilometre Array ...
    • Direct current conductor corona modelling and metrology 

      Otto, Abraham Johannes (Stellenbosch : University of Stellenbosch, 2009-12)
      ENGLISH ABSTRACT: Prospects of up-rating existing high voltage direct current (HVDC) transmission schemes, as well as the conversion of existing alternating current (AC) to direct current (DC) lines and the development ...
    • Lightning protection and radio frequency interference mitigation for the Karoo Array Telescope 

      Wiid, P. Gideon (Stellenbosch : University of Stellenbosch, 2010-03)
      ENGLISH ABSTRACT: South Africa and Australia are now the two remaining countries bidding for the Square Kilometre Array (SKA), the biggest and most sensitive project ever undertaken in radio astronomy. The South African ...
    • Machine learning approach to radio frequency interference(RFI) classification in Radio Astronomy 

      Wolfaardt, Cornelis Johannes (Stellenbosch : Stellenbosch University, 2016-03)
      ENGLISH ABSTRACT: Radio frequency interference (RFI) presents a large problem for radio telescopes. Interference prevents observations from being made, or extends the duration required for observations. This thesis ...
    • Modelling corona noise on high voltage transmission lines 

      Urban, R. G. (Stellenbosch : Stellenbosch University, 2001)
      ENGLISH ABSTRACT: The corona performance of a compact transmission line design must be accurately determined. In particular, the conducted radio interference (RI) noise level will significantly affect the power line ...
    • RFI mitigation in radio astronomy 

      Thompson, Nicholas Christopher (Stellenbosch : Stellenbosch University, 2014-04)
      ENGLISH ABSTRACT: Technical advances in electromagnetics, signal processing and processing power have led to a significant increase in sensitivity and accuracy in radio telescopes. With this increase in sensitivity, radio ...
