| Abstract: |
| This talk is concerned with direct and inverse scattering by an unbounded rough surface with the Dirichlet boundary condition in two dimensions. We study the asymptotics of the solution to the considered scattering problem with the boundary data in a weighted space of continuous functions. Based on this, we develop a direct imaging method for recovering the unbounded rough surface from the scattered-field data generated by incident point sources. Numerical experiments are carried out to demonstrate the feasibility and robustness of our algorithms. |
