Thanks for posting links to the videos and the meetup group, would've joined it years ago if I'd known about it. Quick question, anything radar related in the videos?

Have you seen this: http://www.rtl-sdr.com/passive-radar-dual-coherent-channel-r...

I can't find the link here right now, but there's some more recent work that's doing that without needing the two clock synced receivers too...

Looking at http://www.rtl-sdr.com/tag/passive-radar/ and youtube, it seems like some progress has been made. Not sure if any of the code is open sourced in GNU Radio, Desktop SDR or http://www.rtl-sdr.com/big-list-rtl-sdr-supported-software/ Will look into it more, it's been 2+ years since the last time.
