Inverse acoustic scattering for random obstacles with multi-frequency data
Zhiqi Sun, Xiang Xu, Yiwen Lin
We study an inverse random obstacle scattering problems in where the scatterer is formulated by a Gaussian process defined on the angular parameter domain. Equipped…

An inverse random diffraction grating problem for the Helmholtz equation
Zhiqi Sun, Yiwen Lin
This paper investigates the inverse scattering problem of time-harmonic plane waves incident on a perfectly reflecting random periodic structure. To simulate random perturbations a…
