Darpa Wants to See Inside Your HousePosted: October 24, 2008
While I was reading this I had to ask myself………what is the U.S. military doing operating on U.S. soil? What about Posse comitatus, you know that law passed in 1878 to prevent the military from doing law enforcement inside the U.S. borders? If you don’t know what Posse Comitatus is Read Here:
Darpa Wants to See Inside Your House
The Pentagon wants to be able to peer inside your apartment building — picking out where all the major rooms, stairways, and dens of evil-doers are.
The U.S. military is getting better and better at spotting its enemies, when they’re roaming around the streets. But once those foes duck into houses, they become a whole lot harder to spot. That’s why Darpa, the Defense Department’s way-out research arm, is looking to develop a suite of tools for “external sensing deep inside buildings.” The ultimate goal of this Harnessing Infrastructure for Building Reconnaissance (HIBR) project: “reverse the adversaries’ advantage of urban familiarity and sanctuary and provide U.S. Forces with complete above- and below-ground awareness.”
Darpa doesn’t come out and say it openly. But it appears that the agency wants these HIBR gadgets to be able to track the people inside these buildings, as well. Why else would these sensors be required to “provide real-time updates” once U.S. troops enter the building? Perhaps there’s more about the people-spotting tech, in the “classified appendix” to HIBR’s request for proposals.
Darpa’s Visibuilding program uses a kind of radar to scan structures. The problem isn’t sending the radio frequency (RF) energy in. It’s “making sense of the data produced from all the reflected signals” that come back, Henry Kenyon wrote in a recent Signal magazine article. Besides processing data from the inside a structure, the system also must filter a large amount of RF propagation in the form of randomly reflected signals. Although radar technologies exist that can track people in adjacent rooms, it is much more difficult to map an entire building. “Going through one wall is not that bad, but a building is basically an RF hall of mirrors. You’ve got signals bouncing all over the place,” Darpa program manager Dr. Edward J. Baranoski says. Field trials are supposed to get underway this fall.
