Terence James Elkins

Terence James Elkins (born 8 March 1936) is an Australian-born American physicist. In 1960, he participated in an expedition from Mawson Station which conducted the first geological surveys of the Napier Mountains in Enderby Land, East Antarctica. The highest of this group of mountains, Mount Elkins, was subsequently named after him. In 1979, he received the Harold Brown Award, the United States Air Force's highest honor for research and development, for research he conducted that contributed to the development of the AN/FPS-115, AN/FPS-117 and AN/FPS-118 over-the-horizon backscatter (OTH-B) air defense radar system. Designed to replace the aging Ballistic Missile Early Warning System, these systems are among the most powerful early-warning radar systems ever developed.
