Approximate global convergence and quasi-reversibility for a coefficient inverse problem with backscattering data

Artikel i vetenskaplig tidskrift, 2012

A numerical method possessing the approximate global convergence property is developed for a 3-D coefficient inverse problem for hyperbolic partial differential equations with backscattering data resulting from a single measurement. An important part of this technique is the quasireversibility method. An approximate global convergence theorem is proved. Results of two numerical experiments are presented.
