Universal Software Radio Peripheral aka "Software Defined Radar"

This is such a fascinating project, I don't even know where to begin. It reminds me alot of the kinds of things that were done alot in the earlier days of computing, with guys just throwing together crazy hardware/software hybrids to do the most bizarre things for no other reason than just to see if it could be done. But of course, this has a myriad of applications. Some concerns are cited in the comments below the article, but not the least of which is how this will be treated by the various industrial lobbyists, and in turn, the government's regulatory arm in the form of bans against this sort of "cowboy radio" hijacking or whatever you want to call it. Best part though, is that it doesn't actually break any laws, I don't think, because it doesn't actually capture usable data, it simply takes note of the signal and the physics data associated with the physical signal. For now, anyway... <grin>
