Accuracy vs. Complexity: Calibrating radio interferometer arrays with non-homogeneous element patterns
Jake L. Jones, Randall B. Wayth
Radio interferometer arrays with non-homogeneous element patterns are more difficult to calibrate compared to the more common homogeneous array. In particular, the non-homogeneity…
