In this paper, we investigate the calibration of radio interferometers inwhich Jones matrices are considered to model the interaction between theincident electromagnetic field and the antennas of each station. Specifically,perturbation effects are introduced along the signal path, leading to theconversion of the plane wave into an electric voltage by the receptor. In orderto design a robust estimator, the noise is assumed to follow a sphericallyinvariant random process (SIRP). The derived algorithm is based on an iterativerelaxed concentrated maximum likelihood estimator (MLE), for which closed-formexpressions are obtained for most of the unknown parameters.
