Pentagon's Urban Recon Takes Wing

A leading defense contractor has successfully demonstrated a system that lets foot soldiers command unmanned aerial vehicles, or UAVs, to see real-time overhead images on their handheld computers while fighting in urban battle zones.
Individual war fighters can receive video-surveillance data on a target of interest by moving a cursor over the subject, as part of a Northrop Grumman system to automate reconnaissance, surveillance and target acquisition, or RSTA, within urban environments.
UAVs have already proven their worth in the kinds of urban battle zones that produce daily headlines out of Iraq -- places like Falluja and Najaf, where the drones can navigate the labyrinth of streets or stealthily peer into buildings. But ground troops don't currently have direct access to this surveillance and reconnaissance data, and they have no control of the aircraft that deliver it.
That's what HURT, for Heterogeneous Urban RSTA, promises to change. Northrop demonstrated the system this fall on the former site of Georgia Air Force Base in Victorville, California, on a grid of abandoned streets and buildings used to train soldiers in urban combat.
Two fixed-wing UAVs, a Raven and a Pointer, along with an Rmax rotorcraft, were put aloft under the control of the system. Participants on the ground were able to view wide-area surveillance of the battle zone on handheld monitors, but could also send one of the UAVs in for a closer look at a suspected enemy position by merely moving over the subject with their cursor.
For the demo, a soldier observed a distant garage with a van backing out of it, and selected this target on his handheld screen. HURT autonomously selected the best UAV for the job based on location, and dispatched it to "shadow" the van. It also re-tasked the remaining three aerial units to secure a wide-area perimeter.
"This is truly the system of systems," said Jim Hart, a spokesman for Northrop Grumman. "There is a simple interface that allows it to take just about any kind of ground or air-based sensor platform into its web."
The elasticity of the HURT concept means that UAVs plugged into the system don't need any special modification. The system could also combine ground-based surveillance sensors with airborne platforms, with the potential to reduce manpower demands and risks to friendly forces associated with urban operations, according to a report by Rand.
HURT can also store captured images -- sort of like a battlefield TiVo -- for playback on demand by any user.
To generate the handheld computer's onscreen virtual cities, urban landscape models had to be created using 3-D datasets like the ones used for the high-res images that make Xbox or PlayStation games so visually compelling.
"We've done applications for both the military and consumer markets," said David Colleen, CEO of Planet 9 Studios. "We love the challenge of field applications like this, because they're so much more complex."
HURT is presently concerned only with intelligence gathering, but its versatility means it has the future potential to be used in offensive roles, like coordinating UAVs with tactical-strike capabilities, such as the RQ-1 Predator.
Industry leaders such as Honeywell and AeroVironment are developing micro-UAVs that can loiter in the air and stare in windows, and larger "payload agnostic" units that could play a more offensive role, such as target designation for laser-guided munitions.
Off the battlefield, HURT might one day extend the reach of U.S. homeland-security agencies, providing an airborne surveillance platform equipped with biometric imaging capability and other antiterrorism hardware.
U.S. Customs and Border Protection units could adapt the technology to use networks of ground-based sensors and UAVs equipped with synthetic aperture radar along the border, said Hart.
