Astrophysics, abstract astro-ph/0408473

SETI with SKA would be by far the most powerful SETI search
ever undertaken, covering enough stars with enough sensitivity
to probe significantly further towards those
other Earth civilisations than previous ones.
This paper discusses the rationale behind radio SETI searches,
and explains why SKA will be such as big step forward and
will make few demands on telescope time.

That will be a "kick ass" antenna system !!!
Sorry for bad language, being watching too much
south park recently.

Lol. It would have 81dB gain at 1Ghz and around 97dB at 2Ghz. Enough for natural sources, I hope it would prove useful also for SETI activities.

That would give us quite a bit of work to do ..... hmmmm

This may be a dumb question:

When you point a telescope like Arecibo or Keck or this future SKA at a point in the sky, can only one type of observation be taken?

Let's say a scientist interested in, say cosmic background radiation, points the telescope at some random point. While our theoretical scientist is collecting his radiation data, can the same telescope be used for recording radiowaves for SETI in parallel?

Depends on the projects and the telescope. Seti@home has actually only had some 50 hours of observation time over the past 5 years the rest of the data was collected as a side product of other peoples observation time. Arecibo has a second feed reciever for seti that just points wherever the telescope is pointed. Parkes in austrailia will work on this same principal. Keck is an optical telescope and therefore not suitable for the current incarnation of seti@home but the data may be usefull in other ways. The SKA is (will be) an infered telescope. I don't know if it will be possible to piggyback a seti reciever on it since there is not a single focal point.
