    • Wavefront curvature ranging as a passive synthetic aperture problem 

      Sullivan, Edward J. (NATO. SACLANTCEN, 1997)
      A new method of wavefront curvature passive ranging is introduced that is based on a model-based approach. The signal and measurement systems are placed into state-space form, thereby allowing the unknown parameters of the ...

    • Wavelet analysis of side scan sonar imagery for classification 

      Impagliazzo, John; Greene, Walter; Huynh, Quyen (NATO. SACLANTCEN, 1997)
      Wavelet-based techniques are presented for compressing side scan sonar images communicated from UUV's through band limited communication channels. Testing with an automatrc classifier on reconstructed images demonstrates ...

    • Weather-routing system based on METOC navigation risk assessment 

      Fabbri, Tommaso; Vicen Bueno, Raul (CMRE, 2019/05)
      This paper presents a novel weather-routing system based on a multi-criteria setup. The set of 3 conflicting criteria is: travel time, ship navigation added resistance (caused by wind and waves), and navigation risk/safety. ...
