A DARPA program aimed at preventing attacks involving radiological “dirty bombs” and other nuclear threats has successfully developed and demonstrated a network of smartphone-sized mobile devices that can detect the tiniest traces of radioactive materials. Combined with larger detectors along major roadways, bridges, other fixed infrastructure, and in vehicles, the new networked devices promise significantly enhanced awareness of radiation sources and greater advance warning of possible threats.

Airspace for the flying public today is perpetually congested yet remarkably safe, thanks in no small part to a well-established air traffic control system that tracks, guides and continuously monitors thousands of flights a day. When it comes to small unmanned aerial systems (UAS) such as commercial quadcopters, however, no such comprehensive tracking system exists.

Picture a sensor pixel about the size of a red blood cell. Now envision a million of these pixels—a megapixel’s worth—in an array that covers a thumbnail. Take one more mental trip: dive down onto the surface of the semiconductor hosting all of these pixels and marvel at each pixel’s associated tech-mesh of more than 1,000 integrated transistors, which provide each and every pixel with a tiny reprogrammable brain of its own. That is the vision for DARPA’s new Reconfigurable Imaging (ReImagine) program.

On a recent sunny fall day in the nation’s capital, several hundred volunteers—each toting a backpack containing smartphone-sized radiation detectors—walked for hours around the National Mall searching for clues in a “whodunit” scavenger hunt to locate a geneticist who’d been mysteriously abducted. The geneticist and his abduction were fictitious. But the challenge this scavenger hunt was designed to address is real: The need to detect even small quantities of radioactive material that terrorists might try to bring into an urban area with the intent of detonating a “dirty bomb,” or worse.

In the latest installment of DARPA’s new podcast series, Voices from DARPA, Lindsay Millard discusses the Agency’s Space Surveillance Telescope (SST) program, a key component in the nation’s ability to detect and track space debris and other objects to determine if they will collide with orbiting satellites or impact the Earth.
