Some Operational Formulations for Computational Solutions of Underwater Acoustic Scattering Problems
Abstract
Scattering from ocean wave surfaces, volumes, and bottoms remains a perennial problem not only in underwater acoustics but also in the use of acoustical methods in remote sensing and modeling of the medium itself. Although analytic solutions are sometimes available, in many important cases, particularly those involving multiple scatter and non-isogradiant phenomena including the role of both stationary and moving arrays, and general geometries, effective modeling and quantitative, predictive results ultimately require computational methods. This is true for both deterministic and random media. It is the aim of this introductory study to present a combined analytical- operational framework from which computational procedures are not developed. Rather, the specific aim is to present the 'macro-algorithms' from and to which appropriate software may be designed and applied. Keywords: Operational formulations for propagation and scattering; Underwater acoustic scattering problems; In homogeneous deterministic and random media; Langevin; Dyson; Be the salpeter equations; Perturbation series solutions; Born, Bourret approximations; Formulations for computational solutions; Feedback operational solutions.
