Are you looking at our own Galaxy or at other Galaxies?
A simple question, if there was an intelligent signal coming from a
distant planet how on earth could we get it out from all the noise?
You only have one receiver I am guessing or do you have multiple
receivers like a beamformer? What SNRs are you dealing with (can you
cope with).Has it ever been tested from space ie could voyager or
equivalent give out a signal (at random) and see if the system works?

Thanks
