A Radon-transform-based formula for reconstructing acoustic sources from the scattered fields
Xiaodong Liu, Jing Wang
We propose a novel indicator function for reconstructing acoustic sources from multi-frequency near-field measurements. The theoretical basis is established by a formula relating t…

The Radon Transform-Based Sampling Methods for Biharmonic Sources from the Scattered Fields
Xiaodong Liu, Qingxiang Shi, Jing Wang
This paper presents three quantitative sampling methods for reconstructing extended sources of the biharmonic wave equation using scattered field data. The first method employs an…
