Reconstruct the ambient noise source from the multi-frequency sparse correlation data
Hao Gu, Hongxia Guo, Xiang Xu +1
In this paper, we develop a novel multi-frequency factorization method to reconstruct the spatial support of the ambient noise source. The proposed method only requires sparse corr…
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…
A computational inverse random source problem for elastic waves
Hao Gu, Tianjiao Wang, Xiang Xu +1
This paper investigates the inverse random source problem for elastic waves in three dimensions, where the source is assumed to be driven by an additive white noise. A novel comput…
PML method for the stochastic acoustic scattering problem driven by an additive Gaussian noise
Hongxia Guo, Tianjiao Wang, Xiang Xu +1
This paper is concerned with the time-domain stochastic acoustic scattering problem driven by a spatially white additive Gaussian noise. The main contributions of the work are twof…
