Issue Date: | 2016 | Volume: | Making Space Accessible and Affordable to All Countries | First Page: | 1309 | Abstract: | The Search for ExtraTerrestrial Intelligence (SETI) is a project whose goal is to find possible life signatures emitted (intentionally or unintentionally) by possible civilizations from other habitable planets. Historically, the narrow-band FFT approach has been used, since a quasi-monochromatic signal is the most probable signal one would use to send a message to another world, that is in the case of intentionally- transmitted signals. Nevertheless, we could receive an unintentionally-transmitted signal as well. In that case, it would most certainly not be a quasi-monochromatic signal, but would probably be similar (with a wider bandwidth, of the order of MHz) to the signals that we use for conventional communications on Earth. The Kahrunen-Loève Transform (KLT) is a powerful algorithm for such a kind of research. However, a real-time implementation of the KLT has thus far not worked due to a lack of technological resources. We describe a hardware-software infrastructure at the Sardinia Radio Telescope (SRT) that, in real-time, makes it possible to perform the KLT in parallel to the FFT. | Conference Name: | 67th International Astronautical Congress (IAC 2016) | Conference Place: | Guadalajara, Mexico | Conference Date: | September 26-30, 2016 | URI: | http://hdl.handle.net/20.500.12386/25298 | ISBN: | 978-1-5108-3582-5 | Fulltext: | open |
