The attempt to find out what is the current status of the radar site in Armavir brought somewhat unexpected result - as it turns out, there are two radars there (my thanks to Bernd Reuter, who posted a link to the kosmosnimki.ru image and others who sent me their comments).
These appear to be identical decimeter wave band radars known as Voronezh-DM. One of them is almost completed - this is the one that is looking south-west (azimuth is about 230 degrees - it's hard to measure exactly). As I understand, it has been operating in experimental mode. The other, which will be looking south-east (azimuth about 120-125 degrees), is still under construction.
The structure to the north of the site, which I thought might be the radar site, it is apparently something else.
UPDATE 02/14/09: The first radar is scheduled to begin operations in February 2009.
