What I was saying was that building such a system as originally described is
a daunting task. There are many problems to overcome, one of which is
getting an antenna to work over a 25: 1 bandwidth with reasonably constant
performance.

That's do-able.

Another is that the pattern of the array will change
tremendously over the same bandwidth, but this can be "fixed" by using only
part of the array at higher frequencies.


Yes. Actually not an element problem, but a problem with fixed height above
ground; ground characertistics; mutual coupling; and element spacing--I am sure
you know this; others might not.

Maybe that is why it was "broke up"? Also keep in mind the reputation of
news outlets as to technical accuracy.


My Maser's wasn't so much in antennas (although I did do a bunch of research
to identify the problems and propose solutions), but more at the systems
level to show how digital signal processing can be used to solve previously
"impossible" problems. I recall that at the time the experts in Radio
Astronomy thought the idea wouldn't work at all.

They were wrong; you and Bernard Steinberg (at Valley Forge/UPenn) showed
otherwise:-) BTW, I read your thesis about 10 years ago.Nice work. Others
might also like to know that a synopsis isup on the NAAPO site.

I think the Euro folks are too jazzed by the computational technology end and
have lost sight of the overall goal. That is my personal opinion.
