    • Benchmarking of SCARAB volume scattering versus OASES volume scattering 

      Bratberg, Ivar; LePage, Kevin D.; Holland, Charles W.; Schmidt, Henrik (NATO. SACLANTCEN, 2001/05)
      OASES uses wavenumber integration to solve for the backscattered pressure caused by sound speed and density inhomogeneity scatterers in the sediment; SCARAB uses a ray path technique to find the backscattered intensity. ...

    • Spectral integral representations of scattering from volume inhomogeneities 

      LePage, Kevin D.; Schmidt, Henrik (NATO. SACLANTCEN, 1999/07)
      In-situ measurements of scattering strength can be obtained by analyzing the early-time, high angle reverberation from bottom and sub-bottom features. In order to provide insight into the mechanisms which cause bottom ...
