Picture an intruder stepping stealthily across an international borderline. Now shift to a U.S. Command and Control center several miles away where a computer system is alerting a security officer to the intruder’s movement, having detected the slight sound of a footstep and zeroed in on the intruder’s exact location. The security officer dispatches a UAV to monitor from the air, ground forces to intercept on the ground, and the intruder is stopped.

The detection, classification, location, and tracking system is a recently de-classified covert surveillance and intelligence gathering system, which is now in full-scale development as a result of a licensing agreement between the Naval Undersea Warfare Center (NUWC), Newport, R.I., which invented the sensor technology, and GCS Research of Missoula, Mont., which is further developing and commercializing it.
