A GNU Radio SETI Pipeline for the Allen Telescope Array
summary
A GNU Radio pipeline that streams Allen Telescope Array data from a USRP source, channelises with a polyphase filterbank plus FFT and keeps high-spectral-resolution numpy arrays in RAM, then runs an adapted turboSETI stream directly on 60-second buffers. One-channel tests handle up to ~1 MHz sample rates with turboSETI search times of 1–5 s; a four-channel setup scales to ~404 MHz with searches of 15–20 s. No disk writes; tested on ATA recordings and meets real-time targets.
