Direct imaging methods for reconstructing a locally rough interface from phaseless total-field data or phased far-field data
Long Li, Jiansheng Yang, Bo Zhang +1
This paper is concerned with the problem of inverse scattering of time-harmonic acoustic plane waves by a two-layered medium with a locally rough interface in 2D. A direct imaging…
A Nyström Method for Scattering by a Two-layered Medium with a Rough Boundary
Haiyang Liu, Long Li, Jiansheng Yang +2
This paper is concerned with problems of scattering of time-harmonic acoustic waves by a two-layered medium with a non-locally perturbed boundary (called a rough boundary in this p…
Imaging of buried obstacles in a two-layered medium with phaseless far-field data
Long Li, Jiansheng Yang, Bo Zhang +1
The inverse problem we consider is to reconstruct the location and shape of buried obstacles in the lower half-space of an unbounded two-layered medium in two dimensions from phase…
Fast imaging of scattering obstacles from phaseless far-field measurements at a fixed frequency
Bo Zhang, Haiwen Zhang
This paper is concerned with the inverse obstacle scattering problem with phaseless far-field data at a fixed frequency. The main difficulty of this problem is the so-called transl…
A direct imaging method for inverse elastic scattering by unbounded rigid rough surfaces
Guanghui Hu, Xiaoli Liu, Bo Zhang +1
This paper is concerned with the inverse time-harmonic elastic scattering problem of recovering unbounded rough surfaces in two dimensions. We assume that elastic plane waves with…
Imaging of locally rough surfaces from intensity-only far-field or near-field data
Bo Zhang, Haiwen Zhang
This paper is concerned with a nonlinear imaging problem, which aims to reconstruct a locally perturbed, perfectly reflecting, infinite plane from intensity-only (or phaseless) far…
Recovering scattering obstacles by multi-frequency phaseless far-field data
Bo Zhang, Haiwen Zhang
It is well known that the modulus of the far-field pattern (or phaseless far-field pattern) is invariant under translations of the scattering obstacle if only one plane wave is use…
A Newton method for simultaneous reconstruction of an interface and a buried obstacle from far-field data
Haiwen Zhang, Bo Zhang
This paper is concerned with the inverse problem of scattering of time-harmonic acoustic waves from a penetrable and buried obstacles. By introducing a related transmission scatter…
