Kabina 66 “Back Net”
Air defense radar unit of the former Soviet Union
Interesting at this radar unit is the diametral attachment of 2 antenna systems. Every antenna is meant for another elevation angle. Since two equal radar units always turned a location synchronously, four height ranges were felt therefore (like a Stacked- Beam- Antenna).
The Kabina 66 was coupled with several height-finders (2 - 4 height-finders
PRV-13 or
PRV-17).
The frequency is processed with four impulses but only two of these
are transmitted. Two radar units work synchronizedly as a couple but also separate
operation is possible. The rotary drive is hydraulicly carried out.
The power supply (300 kW / 400 Hz) is carried out of convertor or
with diesel engines. A transfer needs 19 railroad plate freight cars.
