TOPIC: The Russian Woodpecker Over the Horizon Radar – A Blast from the Past
Hidden deep in a serene forest yet taller than the clouds, standing in surreal beauty is an antenna array like none other on earth, having an aperture area greater than 15 U.S. football fields. One of the great wonders of the world – a top secret Soviet radar, so secret that even the name is uncertain, for it had many. It was the Russian Woodpecker. It was the Steel Yard. It was Duga.
The story of this top secret place is one of mystery and intrigue. Now abandoned, a rusting testament to man’s cold war hubris, almost all popular accounts on the web are seriously flawed – victims of deliberate disinformation. Where did it come from? What did it do? Did it transmit? Did it receive? Was it the first of three, or the third of two?
Keith Snyder, KI6BDR, has been busy reverse engineering to uncover truth before time erases history. Keith shows visible engineering clues that reveal the mission and correct the history of the huge “Duga 3” antenna Array. The Duga 3 is located a few kilometers from the Chernobyl nuclear power plant site. Although it has fallen into disrepair, it stands today due only to a hasty exit forced by radiation from the Chernobyl nuclear accident. The nuclear accident ironically protected the array from dismantlement, a reprieve from all but the ravages of time. The antenna array today attracts tourists who visit Chernobyl. It is one of the 8th wonders of the world due to its titanic size.
Our speaker, Keith Snyder (KI6BDR), is a master power user of the FEKO numerical electromagnetics code for antenna modeling and analysis. He started using FEKO 18 years ago as user no. 8 in the U.S. and no. 1 at Northrop Grumman. Keith is an expert at reverse engineering antennas using photos and AutoCAD to import complex models into FEKO. Keith studied antennas at The Ohio State University. He had the great fortune of having Professor John Kraus as his electromagnetics instructor. Keith’s aunt was Kraus’s secretary!
Keith graduated from Ohio State in 1980 and picked up a Telecommunications Certificate from U.C. Berkeley. Keith has considerable antenna design experience having worked on a wide variety of antenna applications including: AM antenna matching at Harris Broadcast in Quincy, Illinois; reflector antennas using the NECREF code at GTE in Needham, Massachusetts; patch antenna arrays at Ball Aerospace in Boulder, Colorado; radar antenna design at Aydin Radar in San Jose; broadband antennas at GTE in Mountain View; shaped reflector antennas at Space Systems Loral; and finally antenna and array design and analysis for aircraft and vehicles at Northrop Grumman in Sacramento, San Jose, and San Diego.
