An iterative scheme for imaging acoustic obstacle from phaseless total-field data

<p style='text-indent:20px;'>In this paper, we consider the inverse problem of determining location and shape a sound-soft or sound-hard obstacle from modulus total-field collected on measured curve for an incident point source. We propose system nonlinear integral equations based iterative scheme to reconstruct both obstacle. Several validating numerical examples are provided illustrate effectiveness robustness proposed inversion algorithm.</p>
