  • Kathree, U; Nel, W; Van Rensburg, VJ; Mishra, AK (IEEE Xplore, 2015-10)
    In the field of radar, High Range Resolution (HRR) profiles are often used to improve target tracking accuracy in range and to allow the radar system to produce an image of an object using techniques such as inverse synthetic ...
  • Janse van Rensburg, V; Mishra, A; Nel, W (2013-05)
    Some Inverse Synthetic Aperture Radar (ISAR) algorithms form the image in a two-step process of range alignment and phase conjugation. This paper discusses a comprehensive set of measures used to quantify the quality of ...
  • Nel, W; Giusti, E; Martorella, M; Abdul Gaffar, MY (IEEE, 2011-10)
    Autofocus is a well known required step in ISAR (and SAR) processing to compensate translational motion. This research proposes a time domain autofocus algorithm and discusses its relation to the well known phase gradient ...
