A new handheld radar scope from the Defense Advanced Research Projects Agency (DARPA) can provide troops with an ability that was formerly the province of science fictional superheroes alone—the ability to sense through up to 12 inches of concrete whether someone is in the next room.
The Radar Scope is expected to be in use in Iraq by spring of this year, according to DARPA's Edward Baranoski. Weighing just 1.5 pounds, the device is about the size of a telephone handset and will cost about $1,000. Waterproof and rugged, it runs on AA batteries. Held up to a wall, users will be able to sense movements as small as breathing up to fifty feet into the next room. "It may not change how four-man stacks go into a room (during clearing operations)," Baranoski said. "But as they go into a building, it can help them prioritize what rooms they go into. It will give them an extra degree of knowledge so they know if someone is inside."
