Reconstruct the ambient noise source from the multi-frequency sparse correlation data
Hao Gu, Hongxia Guo, Xiang Xu +1
The paper proposes a multi‑frequency factorization technique that can recover the shape of an ambient noise source using only a few correlation measurements, with low computational…

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…
