Using multiple beams to identify radio frequency interference in the search for extraterrestrial intelligence

The Allen Telescope Array (ATA) is a multiuser instrument and will perform simultaneous radio astronomy and radio search for extraterrestrial intelligence (SETI) observations. It is a multibeam instrument, with 16 independently steerable dual‐polarization beams at four different tunings. Here we describe a new method for identifying radio frequency interference (RFI) that leverages the unique attributes of the ATA. Given four beams at one tuning, it is possible to distinguish RFI from true ETI…

This paper overviews existing methods for registration of radio signals from distant sources, natural pulsars or artificial SETI signals, implements selected methods as data filters connected to data processing workflow, with 3D Virtual Environment as a frontend and applies them for detection of pulsar signals from BSA telescope at Pushchino Radio Astronomy Observatory and narrow band signals in SETI database setilive.org.
