Multifrequency Array Calibration in Presence of Radio Frequency Interferences
Yassine Mhiri, Mohammed Nabil El Korso, Arnaud Breloy +1
Radio interferometers are phased arrays producing high-resolution images from the covariance matrix of measurements. Calibration of such instruments is necessary and is a critical…
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…
Parallel Calibration for Sensor Array Radio Interferometers
Martin Brossard, Mohammed Nabil El Korso, Marius Pesavento +3
In order to meet the theoretically achievable imaging performance, calibration of modern radio interferometers is a mandatory challenge, especially at low frequencies. In this pers…
Relaxed concentrated MLE for robust calibration of radio interferometers
Virginie Ollier, Mohammed Nabil El Korso, Rémy Boyer +2
In this paper, we investigate the calibration of radio interferometers in which Jones matrices are considered to model the interaction between the incident electromagnetic field an…
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…
