SETI绕过的问题如何lem of radio noise?

Well in fact, our signals are contaminated and that's why, at the SETI Institute, using the Allen Telescope Array, we do our signal processing in near real-time and we keep very good databases of all of the signals that we found and have seen recently. And we do a lot of comparison, a lot of reclassification, and then if we think it's something we haven't seen before, we actually immediately go back and look again. And we look on source, we look off source while the signal is likely to still be persistent, we chase it down.
