Passive Imaging with Ambient Noise Under Wave Speed Mismatch: Mathematical Analysis and Wave Speed Estimation
Zetao Fei, Josselin Garnier
It is known that waves generated by ambient noise sources and recorded by passive receivers can be used to image the reflectivities of an unknown medium. However, reconstructing th…

Towards a Theory of Stable Super-Resolution: Model-Based Formulation and Stability Analysis
Zetao Fei, Hai Zhang
In mathematics, a super-resolution problem can be formulated as acquiring high-frequency data from low-frequency measurements. This extrapolation problem in the frequency domain is…

IFF: A Super-resolution Algorithm for Multiple Measurements
Zetao Fei, Hai Zhang
We consider the problem of reconstructing one-dimensional point sources from their Fourier measurements in a bounded interval . This problem is known to be challenging i…
