The Army's Engineer Research and Development Center wants to put radar systems that identify environmental phenomena on unmanned aerial and ground vehicles so they can be used to survey previously inaccessible locations and cover more territory from the air.
Currently, ground-penetrating radar systems are large arrays mounted on the front of military vehicles to detect improvised explosive devices. Smaller commercial versions exist as well.
