Toward a practical demonstration of physics-based beam calibration models - CBFPs and the LOFAR-LBA antenna array radio telescope

Paper i proceeding, 2014

We consider the application of the Characteristic Basis Function Pattern (CBFP) method to calibrate for direction-dependent gain effects of the LOFAR Low Band Antenna (LBA) array. The use of array-based calibration models, as opposed to element-based calibration models, is proposed in order to reduce the number of solvable beam model parameters.
