North Atlantic Radio System : ウィキペディア英語版 | North Atlantic Radio System The North Atlantic Radio System (NARS) was a chain of five tropospheric scatter communication sites that stretched from Iceland to RAF Fylingdales, forming an extension of the Distant Early Warning Line (DEW Line). ==Development== Built for the United States Air Force (USAF) during the early 1960s by Western Electric (AT&T), the sites were maintained under contract by ITT Federal Electric Corporation (now ITT Federal Services Corp.).〔http://www.northatlanticradiosystem.com/abtnars.htm〕 The NARS network relayed Air-Defence radar data from co-located radars at each site, sending and receiving data via large fixed billboard style antennae, which bounced their signals off the bottom of the Troposphere, hence tropospheric scatter. Although not a part of the (DEW Line), the NARS connected with the North American network at the common DYE-5/NARS 41 Site in Iceland. It also provided connectivity for the Ballistic Missile Early Warning System (BMEWS) site at RAF Fylingdales.〔
