论文摘要
由于新兴的无线电干涉（RI）望远镜（例如平方公里阵列（SKA）），射电天文学正在过渡到大数据时代，该望远镜将获得大量数据。在本文中，我们审查了最近提出的方法，以解决在大数据方案中RI望远镜获得的原始可见性的成像。我们专注于最近提出的在线重建方法[4]及其产生的数据存储要求和计算成本的大量节省。
Radio astronomy is transitioning to a big-data era due to the emerging generation of radio interferometric (RI) telescopes, such as the Square Kilometre Array (SKA), which will acquire massive volumes of data. In this article we review methods proposed recently to resolve the ill-posed inverse problem of imaging the raw visibilities acquired by RI telescopes in the big-data scenario. We focus on the recently proposed online reconstruction method [4] and the considerable savings in data storage requirements and computational cost that it yields.
