Stochastic Expectation Maximization for Robust State-Space Radio Interferometric Imaging
Nawel Arab, Mohammed Nabil El Korso, Isabelle Vin +1
State--space models provide a flexible framework for analyzing dynamical systems, yet they often rely on Gaussian assumptions that fail to capture heavy-tailed or outlier-prone mea…
Robust distributed calibration of radio interferometers with direction dependent distortions
Virginie Ollier, Mohammed Nabil El Korso, André Ferrari +2
In radio astronomy, accurate calibration is of crucial importance for the new generation of radio interferometers. More specifically, because of the potential presence of outliers…
Calibration of Radio Interferometers Using a Sparse DoA Estimation Framework
Martin Brossard, Mohamed Nabil El Korso, Marius Pesavento +2
The calibration of modern radio interferometers is a significant challenge, specifically at low frequencies. In this perspective, we propose a novel iterative calibration algorithm…
