On the numerical stability of the least-squares method for the planar scattering by obstacles
Gilles Chardon
The scattering of waves by obstacles in a 2D setting is considered, in particular the computation of the scattered field via the collocation or the least-squares methods. In the ca…
Imaging With Nature: Compressive Imaging Using a Multiply Scattering Medium
Antoine Liutkus, David Martina, Sébastien Popoff +6
The recent theory of compressive sensing leverages upon the structure of signals to acquire them with much fewer measurements than was previously thought necessary, and certainly w…
Source localization in reverberant rooms using sparse modeling and narrowband measurements
Gilles Chardon, Laurent Daudet
We study two cases of acoustic source localization in a reverberant room, from a number of point-wise narrowband measurements. In the first case, the room is perfectly known. We sh…
Low-complexity computation of plate eigenmodes with Vekua approximations and the Method of Particular Solutions
Gilles Chardon, Laurent Daudet
This paper extends the Method of Particular Solutions (MPS) to the computation of eigenfrequencies and eigenmodes of plates. Specific approximation schemes are developed, with plan…
Sampling and reconstruction of solutions to the Helmholtz equation
Gilles Chardon, Albert Cohen, Laurent Daudet
We consider the inverse problem of reconstructing general solutions to the Helmholtz equation on some domain from their values at scattered points . Thi…
Nearfield Acoustic Holography using sparsity and compressive sampling principles
Gilles Chardon, Laurent Daudet, Antoine Peillot +3
Regularization of the inverse problem is a complex issue when using Near-field Acoustic Holography (NAH) techniques to identify the vibrating sources. This paper shows that, for co…
