在适当的缓冲技术的辅助下，SKA的低频部分可以用作非常高能量的宇宙射线空气簇射的超精密探测器。这将使大量的科学应用成为可能：从银河宇宙射线到河外宇宙射线的跃迁物理学可以用非常高精度的质量测量来探测，强子相互作用可以研究到远远超出人造粒子加速器所能达到的能量，利用大的瞬时带宽和非常均匀的瞬时u$-v$，可以以非常高的空间分辨率执行空气簇射断层成像。SKA 1-LOW的覆盖范围、雷暴的物理学以及宇宙射线与闪电引发之间可能存在的联系，都可以进行前所未有的详细研究。在这篇文章中，我们描述了潜在的SKA作为一个空气簇射无线电探测器从现有的无线电探测工作的角度来看，并讨论了相关的技术要求。
Supplemented with suitable buffering techniques, the low-frequency part of the SKA can be used as an ultra-precise detector for cosmic-ray air showers at very high energies. This would enable a wealth of scientific applications: the physics of the transition from Galactic to extragalactic cosmic rays could be probed with very high precision mass measurements, hadronic interactions could be studied up to energies well beyond the reach of man-made particle accelerators, air shower tomography could be performed with very high spatial resolution exploiting the large instantaneous bandwidth and very uniform instantaneous $u$-$v$ coverage of SKA1-LOW, and the physics of thunderstorms and possible connections between cosmic rays and lightning initiation could be studied in unprecedented levels of detail. In this article, we describe the potential of the SKA as an air shower radio detector from the perspective of existing radio detection efforts and discuss the associated technical requirements.
