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…
Robust Calibration of Radio Interferometers in Non-Gaussian Environment
Virginie Ollier, Mohammed Nabil El Korso, Rémy Boyer +2
The development of new phased array systems in radio astronomy, as the low frequency array (LOFAR) and the square kilometre array (SKA), formed of a large number of small and flexi…
Joint ML calibration and DOA estimation with separated arrays
Virginie Ollier, Mohammed Nabil El Korso, Rémy Boyer +2
This paper investigates parametric direction-of-arrival (DOA) estimation in a particular context: i) each sensor is characterized by an unknown complex gain and ii) the array consi…
