ISEC | 70th Anniversary of Project Diana

Project Diana, named for the Roman moon goddess Diana, was an experimental project of the US Army Signal Corps in 1946 to bounce radar signals off the Moon and receive the reflected signals. This was the first experiment in radar astronomy and the first active attempt to probe another celestial body. It was the inspiration for later EME (Earth-Moon-Earth) communication techniques. On 10 January 1946 at 11:58 AM, Lt. Col. John H. DeWitt and Chief Scientist E. King Stodola sent radio signals toward the moon, and three seconds later, heard their echo. 70 years later, on 10 January 2016 at 11:58 AM, Princeton University Professor Daniel Marlow recreated their experiment using the Cold War vintage TLM-18 antenna system at the same location.
