    • Reduction of low frequency active sonar clutter through image processing 

      Dugelay, S.; Abraham, Douglas A. (NATO. SACLANTCEN, 1997/12)
      Large numbers of false clutter detections arise in the use of low frequency active sonar for the detection of low Doppler submarine targets in shallow water. Traditional detection algorithms operate individually on each ...

    • Single ping clutter reduction: segmentation using Markov random fields 

      Laterveer, Rene (NATO. SACLANTCEN, 1999/03)
      The use of low frequency active sonar in shallow water leads to large numbers of clutter detections. This high false alarm rate can overload automatic tracking and classification algorithms. Traditional detection algorithms ...
