Duga-3 array outside Chernobyl. The array of pairs of cylindrical/conical cages on the right are the driven elements, fed at the facing points with a form of ladder line suspended from stand-off platforms at top right. A backplane reflector of small wires can just be seen left of center, most clearly at the bottom of the image.

Duga-1 ("duga" means "arc") or "Steel Yard" was a Soviet experimental over-the-horizon radar (OTH) system. It was developed for the Soviet ABM early-warning network. The system operated from 1976 to 1989.

The transmitter for the Duga-1 was located approximately 11 kilometers west-northwest of Chernobyl. The receiver was located about 50 km northeast of Chernobyl (just west of Chernihiv, south of Gomel).
