    • Reduction of the antenna coupling in a bi-static, FM-CW radar system 

      Malan, Frederich T (Stellenbosch : Stellenbosch University, 2011-12)
      ENGLISH ABSTRACT: A well-known problem with FM-CW radar systems is the leakage of transmitter power into the receiver which leads to the making of close-in targets, and can severely limit the system dynamic range performance. ...

    • Rekenaargesteunde instelling van gekoppelde-resoneerderfilters deur die gebruik van modelgebaseerde parameteronttrekking 

      Van der Colff, A. P. E. (Stellenbosch : Stellenbosch University, 2002-03)
