    • Bottom/subbottom surveying using a new, parametric, sidescan sonar 

      Wood, Warren T.; Gettrust, Joseph F.; Sen, Mrinal K.; Kosalas, James G. (NATO. SACLANTCEN, 1997)
      The Naval Research Laboratory (NRL) has developed a dual-frequency, towed, interferometric, sidescan sonar system known as the Subbottom Swath System, which is capable of detecting objects and structures buried below the ...
    • Seabed characterization by inversion of parametric sonar data: selection of the cost function 

      Caiti, Andrea; Bergem, Oddbjorn; Pouliquen, Eric; Biancheri, A.; Scaricacciotoli, S. (NATO. SACLANTCEN, 1997)
      A class of possible cost functions to be used in model-based estimation of bottom parameters from highfrequency backscatter signals is introduced. The cost is based on the properttes of the signal in the wavelettransformed ...
