    • Multibeam Echosounder With Orthogonal Waveforms: Feasibility and Potential Benefits 

      Blachet, Antoine; Austeng, Andreas; Aparicio, Joaquin; Hunter, Alan Joseph; Hansen, Roy Edgar (2021-04-15)
      Modern multibeam echosounders (MBE) employ frequency-division techniques (FDT) to ensonify multiple sectors within the same ping cycle. This leads to improved performance in coverage rate, and yaw and pitch stabilization. ...
    • Wideband Synthetic Aperture Sonar Back Projection with Maximization of Wave Number Domain Support 

      Synnes, Stig Asle Vaksvik; Hunter, Alan Joseph; Hansen, Roy Edgar; Sæbø, Torstein Olsmo; Callow, Hayden John; Van Vossen, Robbert; Austeng, Andreas (2017)
      Wideband and widebeam synthetic aperture sonar (SAS) can provide information on the frequency- and aspect-dependent scattering in a scene. We suggest an approach to predict the quality of the sensor data over the available ...
