[hpsdr] And Now for somthing Completly Different

[James Brown]

I was going through some old videos that I made some 25 years ago and came to a talk give by Robert Dixon of the Ohio State 'Big Ear' fame - the place that heard the 'WOW' signal.  He was describing a 'Radio Camera' where he would layout an array of dipoles each closely coupled to a down converter and then the output routed to a central location where there would be a powerful computer to do the FFT and beam forming.  The results would be a picture of the sky that would 'twinkle' as cosmic events happened.  Good idea but with lots of problems as I am sure you understand. He has updated his ideas and they can be found at the  North American Astrophysical Observatory site.

My question is this:
Is there some combination of SDR and antenna technology that could cover part of the microwave spectrum ( say up to 2 gHz) and make something like this finally possible?  Where are the major problems?  I expect - locking the clocks and the needed speed of the A-to-D is the current stumbling blocks.

Any ideas?
