An Efficient Numerical Solution Technique for Wave Propagation in Horizontally Stratified Ocean Environments.
Abstract
This NATO-furnished report presents an efficient numerical solution technique for general applications to wave propagation in horizontally stratified viscoelastic media. The model provides a full-wave solution for the field generated by a single source as well as for that generated by a vertical source array. It allows the spatial distribution of the acoustic field to be evaluated at least one order of magnitude faster than with existing models based on the Thomson-Haskell solution technique. The computational examples clearly demonstrate the model's versatility in providing exact solutions to a wide range of guided and non-guided propagation problems in underwater acoustics, but the model is equally applicable to problems in ultrasonics and seismics. Moreover, the computational efficiency of the numerical code has made it feasible (on array processors) to perform pulse calculations based on Fourier synthesis of time signals, even when hundreds of frequency samples are needed.
