    • AUV technology for shallow water MCM reconnaissance 

      Evans, Benjamin; Baralli, Francesco; Bellettini, Andrea; Bovio, Edoardo; Coiras, Enrique; Davies, Gary L.; Groen, Johannes; Myers, Vincent; Pinto, Marc A. (NURC, 2007/10)
      The ability to perform MCM reconnaissance missions in shallow water is important in both expeditionary MCM and in the protection of ports against maritime improvised explosive devices (MIEDs). For many years AUV systems ...

    • Bathymetric imaging with wideband interferometric synthetic aperture sonar 

      Pinto, Marc A.; Hollett, Reginald D.; Bellettini, Andrea (NATO. SACLANTCEN, 2001/11)
      A new approach to interferometric sonar is presented, based on time delay estimation using shortterm correlation of the seafloor backscatter. It is most suited to signals with large relative bandwidths and long interferometric ...

    • Experimental results of 300 kHz shallow water synthetic aperture sonar 

      Bellettini, Andrea; Pinto, Marc A.; Evans, Benjamin (NURC, 2007/11)
      The design of a shallow water synthetic aperture sonar (SAS) requires an understanding of key system and environmental issues. The main factors which limit SAS performance are micronavigation accuracy, where micronavigation ...

    • Real-and synthetic-array signal processing of buried targets 

      Pinto, Marc A.; Bellettini, Andrea; Hollett, Reginald D.; Tesei, Alessandra (NATO. SACLANTCEN, 2002/01)
      Results from two field experiments aimed at investigating the detection and classification of buried targets are presented. In both experiments a 2-16 kHz parametric source was used. In the first experiment the source was ...

    • Shallow water synthetic aperture sonar: an enabling technology for NATO MCM forces 

      Pinto, Marc A.; Bellettini, Andrea (NURC, 2007/10)
      The change in military focus from Cold War doctrine to expeditionary operations in shallower littoral water and the heightened terrorist threat to ports and their approaches, have put increased emphasis on countering ...
