Abstract

We describe an algorithm for two-dimensional inverse scattering that is based on a finite element approximation of the scalar Helmholtz equation. The algorithm is iterative, so that nonlinearity in the direct scattering can be accounted for, but computationally, the method is slow and, at present, is limited to small problems. Nevertheless, model simulations indicate that the algorithm can produce accurate reconstructions in cases where high-resolution linear methods cannot be applied.
