Correlation between SKA1-LOW stations including mutual coupling

Correlation between SKA-LOW stations is studied in this paper. The mutual coupling is taken into account via embedded element patterns obtained from the simulation of the whole stations. To reduce the sidelobes in the correlated pattern, a rotation of stations is implemented. This results in a smoother behavior in the sidelobe region. Moreover, the spherical-wave expansion is exploited to represent station beam pattern, which then facilitates the correlation between stations.
