Small world! I’m
working on my masters at the Colorado
Springs campus in remote sensing. Although, I’m
waiting to see how the Near Space agreement works out with the Air Force, the bistatic
radar seems like a good second choice (or combo) for an area of research.

We have been doing bistatic radar (technical term for passive radar)
using GPS signals. There are of course other signals out there that
are useful for bistatic radar, and that is my primary reason for
interest in gnuradio modules and the USRP/dbsrx. Our bistatic radar
work is for remote sensing
Krys,

On your webpage, you mention having some GPS data, do you mind sending
it thru email to me. If you want I can let you upload to my ftp
Yes. I was just giving a plug for using H.232 applications over
Skype and the other messengers.

My plan is to get them all sorted out and to make new tarball release
in the next few days.

Can you say some more about your bistatic radar instruments and/or
provide a pointer?
Thanks,

FYI,
The June 2005 issue of IEE Proceedings - Radar, Sonar and Navigation,
volume 152, issue 3 is all about Passive RADAR.
Here's the abstract from the introduction:

We have the same plan here: purchase a USRP and dbsrx daughterboards
for GPS (GNSS) processing. In the past, we used Zarlink GP2015/2021

(http://www.opengps.net). The GP2015 front end receives C/A only, but
is well designed. The prob
Netmeeting is M$, but it adheres (mostly) to the videoconferencing
protocol (H.323, I think) and will talk to Gnomemeeting. Things like
skype, Yahoo, and M$ Messenger don't use a protocol, so they don't
interoperate well or at all. Gnomemeeting is compliant and will
operate with M$ Netmeeting jus
Using skype is a great idea. Tried it real quick but I can't figure out how
to direct the gnuradio audio to the mic input for skype. I could use a loop
back cable but I still can't get past skype and gnuradio both needing access
to the same speaker. Maybe I can redirect skype speaker to a bogus dev
Try GnomeMeeting instead of netmeeting.

Hi Ben,
Have you taken a look at GNURadio wiki? Specifically the GPS page.

I have some code for software GPS at http://www.kamieniecki.com/krys/gps/
