A fast field model for three-dimensional wave propagation in stratified environments based on the global matrix method
Schmidt, Henrik; Glattetre, John (NATO. SACLANTCEN, 1986/03)A three-dimensional fast field program (FFP) model based on the global matrix method will be presented. Compared to traditional propagator matrix methods, the global matrix method allows for a more efficient, and, furthermore, ... -
Evaluation of experimental techniques for determining the plane wave reflection coefficient at the sea floor
Schmidt, Henrik; Jensen, Finn B. (NATO. SACLANTCEN, 1986/06)One of the most commonly used techniques for determinati on of the geoacoustical properties of the sea bed is the measurement of plane wave reflection coefficients at the ocean bottom. An incident field is pr oduced by ... -
Multistatic bottom reverberation in shallow water
Schmidt, Henrik; Lee, Jaiyong; Fan, Huaiyu; LePage, Kevin D. (NATO. SACLANTCEN, 1997)A wavenumber integration approach to modeling of the full multistatic reverberant field produced by small-scale bottom roughness in stratified shallow water waveguides has been developed. A perturbation approach to rough ... -
Review of numerical models in underwater acoustics including recently developed fast-field program
Jensen, Finn B.; Schmidt, Henrik (NATO. SACLANTCEN, 1984/12)Two papers given by SACLANTCEN personnel at the NATO Advanced Research Workshop on Hybrid Formulation of Wave Propagation and Scattering at Castel Gandolfo, Rome, Italy on 30 August to 3 September 1983 are published as a ... -
Shear properties of ocean sediments determined from numerical modelling of Scholte wave data
Jensen, Finn B.; Schmidt, Henrik (NATO. SACLANTCEN, 1986/06)Recently it has become apparent that shear properties of ocean sediments are most easily determined from measured propagation characteristics of seismic interface waves. We use a newly developed numeri ca l model of wave ... -
Subcritical penetration of narrow Gaussian beams into sediments
Jensen, Finn B.; Schmidt, Henrik (NATO. SACLANTCEN, 1988/03)Complete wave-theory solutions have been obtained numerically for both the reflected and the transmitted fields associated with a narrow Gaussian beam incident on a water-sediment interface near the critical grazing angle. ... -
The use of Love waves to determine the geoacoustic properties of marine sediments
Akal, Tuncay; Schmidt, Henrik; Curzi, P. (NATO. SACLANTCEN, 1986/06)The importance of the geoacoustic properties of marine sediments for low-frequency shallow water propagation is well established. Reliable compressional properties can be obtained from laboratory analysis of collected ...
