Darpa's latest program, Aerial Dragnet, is set to track all unmanned aerial systems (UAS) operating below 1,000 feet in large cities. Using sensors, these systems would'see' over and between buildings in order to trail these vehicles with the goal of combating'UAS-enabled terrorist threats' in urban environments.
