Reconstruct the ambient noise source from the multi-frequency sparse correlation dataHao Gu, Hongxia Guo, Xiang Xu et al.
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 correlation data and has low computational cost. Numerical experiments in two and three dimensions are presented to demonstrate the effectiveness of the proposed method.
