<DIV><FONT face=Calibri>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.

<DIV><FONT face=Calibri>My question is this:</FONT></DIV>
<DIV><FONT face=Calibri>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.</FONT></DIV>
<DIV> </DIV>
<DIV><FONT face=Calibri>Any ideas?</FONT></DIV>
