According to a recent Duke press release, researchers at Duke and several other Universities have been awarded funding by DARPA to develop autonomous robotic sensors; the latest in a series of counterterrorism research initiatives. Networks of stationary and mobile sensors deployed on UAVs and ground vehicles would autonomously coordinate data. The sensors would scan for electromagnetic and infrared signatures and use a new mathematic technique called "reverse time migration" to find the origin of the sensor data even when it comes from targets hidden in caves, bunkers, or even trees.
