\"\"<\/p>\n

An RFI-mitigation scheme based on an adaptive filter has been developed for the Parkes Observatory. It was used with good results until the source of interference (a TV transmitter) was decommissioned – at best replica watches which point the system was dismantled.<\/p>\n

A new design is underway for the new ‘ultra-wide bandwidth’ receiver now being built.<\/p>\n

I will also describe a proof-of-concept prototype filter that was trialled at the 6-antenna array at Narrabri – the trial was successful, but challenges remain.<\/p>\n","protected":false},"template":"","class_list":["post-4663","seminari","type-seminari","status-publish","hentry","categorie_seminari-colloquium"],"acf":[],"_links":{"self":[{"href":"https:\/\/www.oa-cagliari.inaf.it\/en\/wp-json\/wp\/v2\/seminari\/4663","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/www.oa-cagliari.inaf.it\/en\/wp-json\/wp\/v2\/seminari"}],"about":[{"href":"https:\/\/www.oa-cagliari.inaf.it\/en\/wp-json\/wp\/v2\/types\/seminari"}],"wp:attachment":[{"href":"https:\/\/www.oa-cagliari.inaf.it\/en\/wp-json\/wp\/v2\/media?parent=4663"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
