Data pubblicazione: | 2017 | Rivista: | MEMORIE DELLA SOCIETA ASTRONOMICA ITALIANA | Numero: | 88 | Fascicolo: | 2 | Da pagina:: | 206 | Abstract: | In radio astronomy Field Programmable Gate Array (FPGA) technology is largely used for the implementation of digital signal processing techniques applied to antenna arrays. This is mainly due to the good trade-off among computing resources, power consumption and cost offered by FPGA chip compared to other technologies like ASIC, GPU and CPU. In the last years several digital backend systems based on such devices have been developed at the Medicina radio astronomical station (INAF-IRA, Bologna, Italy). Instruments like FX correlator, direct imager, beamformer, multi-beam system have been successfully designed and realized on CASPER (Collaboration for Astronomy Signal Processing and Electronics Research, https://casper.berkeley.edu) processing boards. In this paper we present the gained experience in this kind of applications. | URI: | http://hdl.handle.net/20.500.12386/26971 | URL: | http://sait.oat.ts.astro.it/MSAIt880217/index.html | ISSN: | 0037-8720 | Bibcode ADS: | 2017MmSAI..88..206N | Fulltext: | open |
