Direct Method for Identification of Two Coefficients of Acoustic Equation

Direct Method for Identification of Two Coefficients of Acoustic Equation

We consider the coefficient inverse problem for the 2D acoustic equation. The problem is recovering the speed of sound in the medium (which depends only on the depth) and the density (function of both variables). We describe the method, based on the Gelfand–Levitan–Krein approach, which allows us to...
