The low frequency segment of SKA in Australia will have an extremely dense antenna array
spanning an area of roughly 0.5 km2 . It offffers unique possibilities for high-resolution observations
of air showers. Compared to LOFAR, it will have a much more homogeneous ground coverage,
an increased frequency bandwidth (50–350 MHz), and the possibility to continuously observe
with nearly 100% duty cycle. SKA will observe air showers in the range 1016 eV – 1018 eV
with a reconstruction resolution on Xmax of around 10 g/cm2 . This allows for a high-precision
study of mass composition in the energy regime where a transition is expected from Galactic
to extragalactic origin. In addition, SKA will be able to put constraints on hadronic interaction
models, which is crucial for interpreting the data in this complex energy range. In this talk, we will
show the results of a full detector simulation and demonstrate the capabilities of SKA, including
energy and Xmax reconstruction, as well as more advanced methods to constrain the shape of the
longitudinal development of air showers.
