radio-frequency interference Archives

Full-cadence dynamic spectra for the two false-positive events found in the reduced Choza et al. (2024) data set, with time from the beginning of the observation on the y-axis and frequency offset from the starting frequency of the event on the x-axis. Each block in a stack is one of the six pointings that make up the ABACAD observing cadence. The event from the DDO 210 observation was also found by Choza et al. (2024), while the event from the NGC 628 observation is new. -- astro-ph.IM

Anomaly Detection and RFI Classification with Unsupervised Learning in Narrowband Radio Technosignature Searches

by Keith CowingNovember 29, 2024November 29, 2024

The search for radio technosignatures is an anomaly detection problem: candidate signals represent needles of interest in the proverbial haystack of radio-frequency interference (RFI).
