Ska Imaging

In this memo, we explore the imaging requirements and data processing options for the large N SKA. We discuss imaging from the sampled cross correlation function and direct imaging by beam formation. Cross correlation of all antennas provides the most complete sampling of the incident wavefront and allows imaging the full field of view of the individual antennas. Extrapolation of existing and p...
