Issue Date: | 2018 | Journal: | JOURNAL OF ASTRONOMICAL INSTRUMENTATION | Number: | 7 | Issue: | 1 | First Page: | 1850004 | Abstract: | The Sardinia Radio Telescope (SRT) is a 64-m, fully-steerable single-dish radio telescope that was recently commissioned both technically and scientifically with regard to the basic observing modes. In order to improve the scientific capability and cover all the requirements for an advanced single-dish radio telescope, we developed the SArdinia Roach2-based Digital Architecture for Radio Astronomy (SARDARA), a wide-band, multi-feed, general-purpose, and reconfigurable digital platform, whose preliminary setup was used in the early science program of the SRT in 2016. In this paper, we describe the backend both in terms of its scientific motivation and technical design, how it has been interfaced with the telescope environment during its development and, finally, its scientific commissioning in different observing modes with single- feed receivers. | URI: | http://hdl.handle.net/20.500.12386/29483 | URL: | https://www.worldscientific.com/doi/full/10.1142/S2251171718500046 | ISSN: | 2251-1725 | DOI: | 10.1142/S2251171718500046 | Bibcode ADS: | 2018JAI.....750004M | Fulltext: | open |
