I'm one of the folks wanting to use USRP/GnuRadio for amateur radio
astronomy. Nice to see you
"on board" with the GnuRadio project. I actually paid a tourist
visit to the VLA a couple of years
ago, and bumped into one of your public-education folks.
I also just got my copy of "Synthesis Imaging in Radio Astronomy II"
didn't I see your name in
the credits?
There is a fair number of us tooling up to use USRP/GnuRadio
combinations for amateur
RA work, and it's good to see an increasing number of professional
radio astronomy
types joining the "GnuRadio" revolution.
I built an agile receiver a couple of years ago, but the spectral
bandwidth sucked, so I waited patiently
for the USRP to come to fruition. My winter project is to get my
USRP working to at least the
same degree of functionality I had with my receiver
(http://www.propulsionpolymers.com/radioastronomy/
seti_receiver.pdf). My primary interest is actual "conventional" RA,
but the spectral capabilities
were interesting to the amateur SETI crowd, which is how I slanted my
paper.
I at a far too low level to have anything in that book. I also came here
only 7 years ago.
I'm an electronics designer as opposed to a theoretical type or
astronomer. I have taken the summer school that uses the book you mention.
Most of the people who did write the book are still around. Barry Clark
is emeritus now for about a year but still shows up at work most of the
time.
The local college here (New Mexico Tech) has a two antenna
interferometer a short walk from my home. I got two of the DBS daughter
cards for my USRP with the idea of someday hooking them up to the antennas.
I'll eventually have to write some kind of correlator to get fringes.
