Paper Abstract

In this paper we consider the back-propagation algorithm of Devaney which is based on the Rytov approximation. To examine its validity we first generate scattered data using exact solutions for acoustic scattering by a penetrable elliptic cylinder. We then run these data through the inversion algorithm to find the reconstructed object. In this manner we determine how the accuracy of the algorithm depends on the wavelength of the incident wave and the number of views employed, as well as on the size, geometry and contrast of the object.
