Locating a complex inhomogeneous medium with an approximate factorization method
Fenglong Qu, Haiwen Zhang
Consider the inverse problem of scattering of time-harmonic acoustic waves by an inhomogeneous medium with complex refractive index. We show that an approximate factorization metho…
Uniqueness and direct imaging method for inverse scattering by locally rough surfaces with phaseless near-field data
Xiaoxu Xu, Bo Zhang, Haiwen Zhang
This paper is concerned with inverse scattering of plane waves by a locally perturbed infinite plane (which is called a locally rough surface) with the modulus of the total-field d…
Uniqueness in inverse scattering problems with phaseless far-field data at a fixed frequency. II
Xiaoxu Xu, Bo Zhang, Haiwen Zhang
This paper is concerned with uniqueness in inverse acoustic scattering with phaseless far-field data at a fixed frequency. In our previous work ({\em SIAM J. Appl. Math. \bf78} (20…
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…
Near-field imaging of an unbounded elastic rough surface with a direct imaging method
Xiaoli Liu, Bo Zhang, Haiwen Zhang
This paper is concerned with the inverse scattering problem of time-harmonic elastic waves by an unbounded rigid rough surface. A direct imaging method is developed to reconstruct…
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…
A direct imaging method for inverse scattering by unbounded rough surfaces
Xiaoli Liu, Bo Zhang, Haiwen Zhang
This paper is concerned with the inverse scattering problem by an unbounded rough surface. A direct imaging method is proposed to reconstruct the rough surface from the scattered n…
