    • 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 ...

    • Parametric relations on FM sonar 

      Kelly, H. W. K. (NATO. SACLANTCEN, 1961/06)
      The report deals with the simple theory of FM sonar operations and shows how an optimum system may be designed. It also indicates the effects of doppler, the equipment and other factors which may be expected, in practice, ...

    • 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 ...
