Multi-frequency calibration for DOA estimation with distributed sensors
Martin Brossard, Virginie Ollier, Mohammed Nabil El Korso +2
In this work, we investigate direction finding in the presence of sensor gain uncertainties and directional perturbations for sensor array processing in a multi-frequency scenario.…
Asymptotic Performance of Complex M-estimators for Multivariate Location and Scatter Estimation
Bruno Mériaux, Chengfang Ren, Mohammed Nabil El Korso +2
The joint estimation of means and scatter matrices is often a core problem in multivariate analysis. In order to overcome robustness issues, such as outliers from Gaussian assumpti…
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…
