Acoustic and geoacoustic inverse problems in randomly perturbed shallow-water environments
Laure Dumaz, Josselin Garnier, Guilhem Lepoultier
The main goal of this paper is to estimate the regional acoustic and geoacoustic shallow-water environment from data collected by a vertical hydrophone array and transmitted by dis…
Wave propagation in randomly perturbed weakly coupled waveguides
Liliana Borcea, Josselin Garnier
We present an analysis of wave propagation in a two step-index, parallel waveguide system. The goal is to quantify the effect of scattering at randomly perturbed interfaces between…
Wave propagation and imaging in moving random media
Liliana Borcea, Josselin Garnier, Knut Solna
We present a study of sound wave propagation in a time dependent random medium and an application to imaging. The medium is modeled by small temporal and spatial random fluctuation…
Imaging through a scattering medium by speckle intensity correlations
Josselin Garnier, Knut Solna
In this paper we analyze an imaging technique based on intensity speckle correlations over incident field position proposed in [J. A. Newmann and K. J. Webb, Phys. Rev. Lett. 113,…
A ghost imaging modality in a random waveguide
Liliana Borcea, Josselin Garnier
We study the imaging of a penetrable scatterer, aka target, in a waveguide with randomly perturbed boundary. The target is located between a partially coherent source which transmi…
