Numerical solution of the direct scattering problem through the transformed acoustical wave equation.

S Pourjavid1, O J Tretiak.   

Abstract

A transformation is applied to the acoustical wave equation to obtain a new equivalent form that does not contain gradients of the pressure. A new technique, based on the spectral method, is developed for the numerical solution of the direct time domain scattering problem. Modeling techniques for obtaining accurate solutions are discussed and numerical examples are presented.
