Imagine if you will a terrorist cell getting their hands on a drone, or a number of them, and some explosives. No, this is not an episode of 24. The military calls drones unmanned aerial systems (UAS), and they are worried about them. While planes and helicopters are large enough to recognize easily on radar, drones, being smaller, can be mistaken for birds.
That’s why the Pentagon’s R&D wing has been tapped to create a system to protect soldiers on the battlefield and civilians at home, from this ever-growing threat. The Defense Advanced Research Projects Agency (DARPA), the people who brought you the internet and many other startling innovations, have an idea on how to stop “UAS-enabled terrorist threats.” What DARPA is doing is requesting proposals for something they are calling an “aerial dragnet.”
The DARPA announced their request via FedBizOpps and in a press release, DARPA officials stated –
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. And as off-the-shelf UAS become less expensive, easier to fly, and more adaptable for terrorist or military purposes, U.S. forces will increasingly be challenged by the need to quickly detect and identify such craft—especially in urban areas, where sight lines are limited and many objects may be moving at similar speeds.
To achieve the technically difficult goal of mapping small UAS in urban terrain, DARPA today announced its Aerial Dragnet program. The program seeks innovative technologies to provide persistent, wide-area surveillance of all UAS operating below 1,000 feet in a large city. While Aerial Dragnet’s focus is on protecting military troops operating in urban settings overseas, the system could ultimately find civilian application to help protect U.S. metropolitan areas from UAS-enabled terrorist threats.

“Commercial websites currently exist that display in real-time the tracks of relatively high and fast aircraft—from small general aviation planes to large airliners—all overlaid on geographical maps as they fly around the country and the world,” said Jeff Krolik, DARPA program manager. “We want a similar capability for identifying and tracking slower, low-flying unmanned aerial systems, particularly in urban environments.”
Although several systems are being developed for tracking small UAS by extending surveillance methods used in open areas where large line-of-sight buffers mitigate the threat, these systems are impractical for operation in urban terrain. Aerial Dragnet seeks to leapfrog these approaches by developing systems adapted to the fundamental physics of small UAS in urban environments that could enable non-line-of-sight (NLOS) tracking and identification of a wide range of slow, low-flying threats. The program seeks an array of innovative approaches, but notionally envisions a network of surveillance nodes, each providing coverage of a neighborhood-sized urban area, perhaps mounted on tethered or long-endurance UAS. Using sensor technologies that can look over and between buildings, the surveillance nodes would maintain UAS tracks even when the craft disappear from sight around corners or behind objects. The output of the Aerial Dragnet system would be a continually updated common operational picture (COP) of the airspace at altitudes below where current aircraft surveillance systems can monitor, disseminated electronically to authorized users via secure data links. Because of the large market for inexpensive small UAS, the program will focus on combining low-cost sensor hardware with software-defined signal processing hosted on existing UAS platforms. The resulting surveillance systems would thus be cost-effectively scalable for larger coverage areas and rapidly upgradable as new, more capable and economical versions of component technologies become available.
The Aerial Dragnet program seeks teams with expertise in sensors, signal processing, and networked autonomy to achieve its goal. A Broad Agency Announcement (BAA) solicitation detailing the goals and technical details of the program was posted on FedBizOps today and is available here:http://go.usa.gov/xBx4A.
