A novel sampling method for reconstruction of a moving point acoustic source in
Guanqiu Ma, Shuang Li, Hongxia Guo
In this paper, we introduce a novel sampling method to recovering the trajectory of a moving point source in R^3, where both the spatial location and emission moment of the moving…
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…
A direct sampling method for inverse time-dependent electromagnetic source problems: reconstruction of the radiating time and spatial support
Fenglin Sun, Hongxia Guo
This paper investigates inverse source problems for time-dependent electromagnetic waves governed by Maxwell's equations. After applying the Fourier transform with respect to time,…
A frequency-domain method to inverse moving source problem with unknown radiating moment
Guanqiu Ma, Hongxia Guo, Guanghui Hu
This paper introduces a multi-frequency factorization method for imaging a time-dependent source, specifically to recover its spatial support and the associated excitation instants…
