The testing, evaluation and training of future military systems will increasingly take place in virtual environments due to rising costs and system complexity as well as the limited availability of military ranges. Virtual simulators are already used to augment real-world training for modern fighter aircraft pilots, and they hold significant promise for addressing the rigorous demands of testing and training AI-enabled technologies. Current simulated environments, however, rely on conventional computing that is incapable of generating the computational throughput and speed to accurately replicate real-world interactions, model the scale of physical test ranges or meet the technical requirements of more complex systems.

X-rays and gamma rays have a wide range of applications including scanning suspicious maritime shipping containers for illicit materials, industrial inspection of materials and processes, and medical diagnostic and therapeutic procedures. Current technologies, however, are not ideal. X-rays produce a continuum of energies that limit their inspection and diagnostic performance, and gamma rays can only be produced at specific energies unique to a given radioactive isotope.

Over the past three years, DARPA’s Spectrum Collaboration Challenge (SC2) has relied on a custom-built virtual testbed called the Colosseum to host thousands of competitive matches and scrimmages, which will include the final match to determine the winner of the $2 million grand prize. Supporting SC2’s mission to reimagine new spectrum access strategies in which radio networks autonomously collaborate to determine how the RF spectrum should be used moment-to-moment required the development of a research environment capable of emulating communication signals at real-world scope and scale.

DARPA today announced the 10 teams that have qualified for the Championship Event of the Spectrum Collaboration Challenge (SC2) – a three-year contest to unlock the potential of the radio frequency (RF) spectrum using artificial intelligence (AI). The teams will head to Mobile World Congress Los Angeles on October 23, 2019, where their radio designs will go head to head during a live competition. The first, second, and third place winners will walk away with $2 million, $1 million, and $750,000 prizes, respectively.
