• Beamforming for radio astronomy 

      Van Tonder, Vereese (Stellenbosch : Stellenbosch University, 2014-12)
      ENGLISH ABSTRACT: Beamforming is a technique used to combine signals from an array of antennas to effectively synthesize a single aperture and beam. In the Radio Astronomy community the technique is used to obtain a ...
    • Beamforming techniques for a quad-mode antenna array 

      Van Tonder, Geomarr (Stellenbosch : Stellenbosch University, 2017-03)
      ENGLISH ABSTRACT: This thesis is based on a quad-mode antenna, designed by a group of researchers from the University of Stellenbosch. The antenna is designed using two co-located dipoles and a cylindrical monopole antenna ...
    • Quantization effects on beamforming in dense phased arrays 

      Wilke, Cornelis Rossouw (Stellenbosch : Stellenbosch University, 2018-03)
      ENGLISH ABSTRACT: Reflector-based radio telescopes have traditionally been the instrument of choice in Radio Astronomy since around the 1960’s. However, in particular for frequencies below around 1 GHz, a new generation ...
