The AACER program will develop extended range ground moving target indication (GMTI) radar combined with a high resolution synthetic aperture radar (SAR) and integrated communications to be used on tactical-level unmanned aerial vehicles (UAVs) such as the U.S. Army's Class IV UAV or the A-160 Hummingbird. The radar will provide unprecedented, high update rates for tracked targets, and persistent stare over large areas with high update rates.

The affordable, adaptive and conformal electronic scanning antenna developed under the AACER program will provide the U.S. Army with enhanced GMTI/SAR systems for reconnaissance, surveillance, target acquisition and tracking missions.

During the initial 12-month phase of the AACER program, the contractors will demonstrate key electronic scanning antenna technology and develop preliminary designs for each radar concept. In phase II, the program will down-select to a single contractor to complete a system design and build key sub-assemblies that meet weight and form factors for the Army's Future Combat Systems Unit of Action Class IV UAV.

During phase III, the program will perform a final system integration and flight test demonstration that will bring forth a new capability for the Army's Future Combat Systems Unit of Action. Although the AACER program is focused on a future Army ground unit capability, the AACER capability may also be useful to other ground forces such as the U.S. Marine Corps and special operations forces.
