The DARPA FORESTER is a technology development program sponsored jointly by the Defense Advanced Research Projects Agency (DARPA) and the U.S. Army intended to produce an advanced airborne UHF radar system that can track personnel and vehicles on the ground when they are hidden by foliage.
[1] The FORESTER is a GMTI radar system with a resolution of 6 meters[2] that is mounted inside a 21.5-foot (6.6 m) long pod and designed to be carried under an A160 Hummingbird helicopter unmanned aerial vehicle (UAV).
[3] The system is able to detect vehicles and walking soldiers underneath tree cover from a distance of 30 miles (48 km), giving battle planners the ability to detect potential ambushes.

Army A160 Hummingbird unmanned aerial vehicle [UAV] helicopter or other suitable platform will provide a robust, wide-area, all-weather, standoff capability.
