Radio-telescopes and support-rotating mechanisms (SRM) of radar complexes ![]()
1. Radio-telescope RATAN-600
RATAN-600 is designed on the basis of reflector-type antennas with variable profile and combines advantages of huge stationary and mobile radio-telescopes. RATAN-600 comprises circular reflector (main reflector), plain reflector (periscope) and irradiators of various design and purpose (secondary reflectors). Circular reflector is a variable-profile antenna and consists of 900 shields installed circum-ferentially with diameter of 600m with continuous reflection power of 2x7,4m each. Each of the shields rotates independently horizontally (in elevation angle) and vertically (in azimuth) and moves in radial direction which provides forming of circular reflector reflecting surface with variable parabola profile.
Circular construction of radio-telescope and its ability to change reflecting surface enable research any sky area.
Deviation of shield reflecting surfaces from theoretical profile is ±0,1mm.
Plain reflector
(periscope) | Length | 400m | | Number of shields | 125pcs | | Dimensions | 3.2x8 m2 | | Circular reflector (main reflector) | Diameter of reflecting elements (shields) location | 600m | | Number of shields | 900pcs | | Shield dimensions | 2x7.4 m2 | | |  |
2. Radio-telescope RTF-32
Radio-telescope is designed for receiving radio-frequency emission of cosmic sources of natural and artificial origin in centimetric wave band to solve astronomy, geodesy, seismology and space navigation tasks.
JSC «Tyazhmash» provides design and mechanical part of the radio telescope.
| Main reflector diameter | 32m | | Subdish diameter | 4m | | Focus distance | 11.4m | | Azimuthal rotation | ±270o | | Rotation in elevation angle | 5 95o | | Overal dimensions | 32x32x40m | | Weight | 600t | | |  |
3. Support-rotating mechanisms (SRM) of radar complexes «UTES-94»
Radar complexes are designed to control air traffic on air routes and aerodrome area.
There are 7 versions of complex construction:
1,2,3 – antenna module under radar dome with ele vation of prime radar phase center (PR) of 28, 22 and 15 meters correspondingly;
| | 4,5,6 – antenna module without radar dome with ele vation of prime radar phase center (PR) of 28, 22 and 15 meters correspondingly;
7 – antenna module on automobile semitrailer with elevation of prime radar phase center (PR) of 7 meters.
