  • Prieur, Fabrice Jean Gabriel; Näsholm, Sven Peter; Austeng, Andreas; Holm, Sverre (Conference object / Konferansebidrag, 2010)
    The 10th European Conference on Underwater Acoustics (ECUA). 2010, Istanbul, Turkey. Mainstream sonars transmit and receive signals at the same frequency. As water is a nonlinear medium, a propagating signal generates ...
  • Blomberg, Ann Elisabeth Albright; Weber, Thomas C.; Austeng, Andreas (Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2018)
    Natural seepage of methane into the oceans is considerable, and plays a role in the global carbon cycle. Estimating the amount of this greenhouse gas entering the water column is important in order to understand their ...
  • Lønmo, Tor Inge Birkenes; Austeng, Andreas; Hansen, Roy Edgar (Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2015)
    Modern sonars provide high-resolution acoustic imaging for a range of applications, including pipeline inspection, harbor surveys and seabed mapping. Central in the signal processing of the sonar data is the beamforming, ...
  • Hverven, Stine Myhre; Rindal, Ole Marius Hoel; Hunter, Alan J.; Austeng, Andreas (Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2017)
    Background speckle can often obscure objects of interest in an ultrasound image. The probability of detection and classification of point scatterers is highly affected by background speckle. The proposed algorithm uses a ...
  • Rodriguez-Molares, Alfonso; Rindal, Ole Marius Hoel; Bernard, Olivier; Nair, Arun; Bell, Muyinatu A. Lediju; Liebgott, Herve; Austeng, Andreas; Løvstakken, Lasse (Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2017)
    We present the UltraSound ToolBox (USTB), a processing framework for ultrasound signals. USTB aims to facilitate the comparison of imaging techniques and the dissemination of research results. It fills the void of tools ...
