Comparison of One-Way Wave Propagation Algorithms in Underwater Acoustics - Error Estimates and Sensitivity
Abstract
The long-range objective is to develop and apply microscopic phase space methods and global path integral constructions to gain a deeper theoretical and computational understanding of acoustic, electromagnetic, and seismic direct and inverse wave propagation problems. This seems to be an appropriate approach for ocean seismo-acoustic modeling, which is characterized by rapidly changing, multidimensional environments extending over many wavelengths. Much of the mathematical development can indeed be motivated by the well-known parabolic (paraxial) approximation. Combining wave field splitting, invariant imbedding, and phase space (pseudo-differential and Fourier integral operator) methods has led to the development of both one- and two-way direct Helmholtz solvers, in addition to providing the framework for multidimensional profile reconstruction algorithms based on exact solution methods.
