A distributed resource-adaptive implementation of the widefield radio-interferometric measurement model for scalable image formation
Arwa Dabbech, Yves Wiaux
Modern image formation algorithms in radio interferometry rely on repeated applications of the operator Φ modelling the measurement process and its adjoint {Phi^\dagger} to enforc…

MROP: Modulated Rank-One Projections for compressive radio interferometric imaging
Olivier Leblanc, Chung San Chu, Laurent Jacques +1
The emerging generation of radio-interferometric (RI) arrays are set to form images of the sky with a new regime of sensitivity and resolution. This implies a significant increase…

Compressive radio-interferometric sensing with random beamforming as rank-one signal covariance projections
Olivier Leblanc, Yves Wiaux, Laurent Jacques
Radio-interferometry (RI) observes the sky at unprecedented angular resolutions, enabling the study of several far-away galactic objects such as galaxies and black holes. In RI, an…
