摘要

Until now the LOFAR (LOw Frequency ARray) radio telescope in the Netherlands used a simple beam model with identical element patterns to calibrate the array (assuming no mutual coupling). To improve the accuracy of the calibration, work has been set in motion to improve the beam model by full-wave electromagnetic simulations. This paper reports the initial commissioning results.
