Exciting a land mine may not sound like a good idea, but developers of the Seismic Landmine Detection System are doing just that. A group of researchers from the Georgia Tech Research Institute in Atlanta, Georgia, has developed a land mine detection system that sends seismic waves through a minefield, slightly moving the earth and items buried beneath. A noncontacting radar sensor measures the ground displacement to identify and locate plastic anti-personnel or antitank mines.

A new generation of highly capable robot aircraft soon may augment and perhaps replace manned platforms in high-threat combat operations such as suppressing enemy air defenses and deep strike missions. These vehicles are part of an ambitious U.S. Defense Department program to develop and field-test an unmanned aerial combat capability by the end of the decade.

A team of researchers from industry, academia and the U.S. Defense Department is creating high-speed, long-range communication technologies that will help eliminate the fog of war and take the element of surprise away from the enemy. The secure laser-based system will offer communication uplink speeds in the multigigabit-per-second range and will improve tracking so communications can be transmitted to satellites from mobile platforms. The research also will lead to aberration-free three-dimensional imaging at distances of more than 600 miles.

The next generation of unmanned aerial vehicles may owe more to winged insects and birds than to the Wright Brothers. U.S. Air Force engineers are tapping nature's flyers for new designs that push the limits of aerodynamics.

Future U.S. Air Force pilots will rely on an extensive array of sensors and interconnected platforms to detect and destroy enemy forces. Lessons learned from recent combat operations over Iraq support the service's network-centric operational concept that envisions shortened sensor-to-shooter cycles, networked weapons and increased information sharing among all echelons.

Network-centric warfare is on the fast track with the U.S. Marine Corps in operation Iraqi Freedom. After mobile operation centers received rave reviews from troops that previewed them in-theater, the service decided to field the equipment months earlier than originally planned, prior to final testing and evaluation. Commanders relate that the capability dramatically improves situational awareness and cuts decision-making time in half.

The U.S. Navy is using a U.S. Defense Department model and wartime experiences to begin defining the network that will close the loop on full network-centric warfare. The FORCEnet program is completing a concept development phase this month, and planners now are able to envision when it will achieve key benchmarks.

The U.S. Army is marching forward double time on several fronts to bring the power of networking to bear on the global war on terrorism. A number of efforts-some technological, others structural-aim at creating an information-based Army that can respond to threats quicker and effectively fight asymmetric enemies. Improved networking capabilities will affect how the service fights-from the individual soldier on the front line to those providing logistical support.

If we really believe a network-centric coalition/joint force offers an opportunity for effects-based conflict in the future-and that this same network-centric force improves lethality, intelligence sharing and command and control-then why aren't we embracing the concept of changing the culture to match the technology capabilities that Free World industry is offering to warfighters in the fight for freedom?

Information security researchers at George Washington University are studying new ways to strengthen identification authentication processes while keeping transactions as simple as possible. The techniques involve deliberate perturbations of traditional authentication processes and can be applied to password, token and biometric systems alike.
