    • Acoustic scattering from rough surfaces 

      Hurdle, B.; Flowers, K. D.; DeSanto, John Anthony (NATO. SACLANTCEN, 1975/10)
      A review of scattering from the ocean bottom and ocean ice cover is given. Areas of deficiency are cited.
    • Connection between the solution of the Helmholtz and parabolic equations for sound propagation 

      DeSanto, John Anthony (NATO. SACLANTCEN, 1975/10)
      Using a conformal mapping technique in a rectangular waveguide, we present an exact integral relation between the solutions of the Helmholtz equation whose sound speed c(x,y) varies as a function of both depth y and range ...
    • Inverse wave propagation in an inhomogeneous waveguide 

      DeSanto, John Anthony (NATO. SACLANTCEN, 1975/10)
      A solution is given for the problem of inverse propagation in an inhomogeneous rectangular two-dimensional waveguide. The sound speed is assumed to vary in depth and inverse propagation means the calculation of the field ...
    • Scattering from a random interface 

      DeSanto, John Anthony (NATO. SACLANTCEN, 1975/10)
      The problem of scattering from a random interface separating two fluids with different densities and sound speeds is considered. The method is to write coupled integral equations in coordinate space connecting the surface ...
