Project Diana January 10, 1946
This was the 1946 beginning of space communications and the birth of the field of Radar Astronomy!!! Accomplished at Camp Evans, the former Marconi Belmar High-powered Wireless Station…
A KEY link in the world’s first wireless network…Where Edwin Armstrong demonstrated his regenerative circuit to David Sarnoff in 1913, proving worldwide wireless reception was possible…
Where radio era greats like Ernst Alexanderson, A. Hoyt Taylor, George Clark, Roy Weagant, Dr. Harold Beverage, Dr. H. O. Peterson, and many others worked to improve communications technology…and the Diana team used equipment supplied by Edwin Armstrong!
Diana RADAR is the bed-spring like device to the right of center Camp Evans. Camp Evans Opened the Space Age in January 1946 with Project Diana.
In late 1945, in the lull that followed the Japanese surrender, a number of scientists at Fort Monmouth’s Camp Evans began working on a way to pierce the earth’s ionosphere with radio waves, a feat that had been tried just before the war without success and which many thought impossible. Project Diana, named for the goddess of the moon, was designed to prove that it could be done. Begun on an almost unofficial level by Evans radar scientists awaiting their Army discharge, the project was headed by Lt. Col. John DeWitt. Operating with only a handful of full-time researched, the project scientists greatly modified an SCR-271 bed-spring radar antenna, set it up in the northeast corner of Camp Evans, jacked up the power, and aimed it at the rising moon on the morning of January 10, 1946. A series of radar signals were broadcast, and in each case, the echo was picked up in exactly 2.5 seconds, the time it takes light to travel to the moon and back.
The importance of Project Diana cannot be overestimated. The discovery that the ionosphere could be pierced and that communication was possible between earth and the universe beyond, opened the possibility of space exploration that previously had been only a dream in adventure films and comic books. Just as Hiroshima opened the nuclear age in 1945, Project Diana opened the space age in January of 1946. It would take another decade before the first satellites were launched into space, soon followed by manned rockets, but Diana paved the way for all those achievements. It even initiated the tradition of naming such projects after ancient Greek and Roman gods, like Mercury and Apollo. For Fort Monmouth Project Diana was a pivotal event that built on World War II expertise but pointed the way to the future. Page 24 &27.

Technical Articles by Project Diana Team in the InfoAge archives…
1) January 1946 technical article with photos – ‘Radar Echoes From the Moon’ By Jack Mofenson Thanks to Harry Visser, who created the page and gave us permission to use it on our site. The article is a… “Detailed description of the techniques underlying the first recorded radio transmission through outer space. Calculations show that the maximum range of the Signal Corps radar on lunar target exceeds one million miles”.
2) Herbert Kauffman authored — ‘A DX Record: To the Moon and Back, How the Moon-Radar Feat has Accomplished ‘ Thanks to Russ Brahn, AE2X we have a copy.
