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…
Bayesian Calibration using Different Prior Distributions: an Iterative Maximum A Posteriori Approach for Radio Interferometers
Virginie Ollier, Mohammed Nabil El Korso, André Ferrari +2
In this paper, we aim to design robust estimation techniques based on the compound-Gaussian (CG) process and adapted for calibration of radio interferometers. The motivation beyond…
Robust Calibration of Radio Interferometers in Multi-Frequency Scenario
Virginie Ollier, Mohammed Nabil El Korso, André Ferrari +2
This paper investigates calibration of sensor arrays in the radio astronomy context. Current and future radio telescopes require computationally efficient algorithms to overcome th…
