Initial Beamforming Analysis for Substations in the SKA-Low Radio Telescope

This paper reports initial work on forming substation beams within the SKA- Low telescope, the lower frequency component of the Square Kilometre Array Observatory. The analysis leverages the embedded element patterns computed for a progression of SKA- Low prototype arrays over several years. The results indicate that the proposed substation layouts form beams as expected. There is detailed structure in these substation beams which can now be evaluated against the requirements for specific science cases.
