Abstract:
The newly refurbished The Allen Telescope Array uses beam-forming within its primary field of view for SETI observations in an effort to discriminate between local radio frequency interference (RFI) and signals localized to the target source. In late October and early November, 2022, 28 hours of observations of the TRAPPIST-1 system were taken and preprocessed in this mode. After processing the filterbank data products with turboSETI’s deDoppler algorithm to identify signals, a new pipeline was created and implemented to handle RFI filtering for this and other high frequency resolution multi-beam observations. This talk will be a look at the methods employed by this pipeline, including identical signal rejection, power correlation, signal to noise calculation, and signal attenuation, and some preliminary results.
