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…

SCAN-MUSIC: An Efficient Super-resolution Algorithm for Single Snapshot Wide-band Line Spectral Estimation
Zetao Fei, Hai Zhang
We propose an efficient algorithm for reconstructing one-dimensional wide-band line spectra from their Fourier data in a bounded interval . While traditional subspace metho…

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 in…
