The RATAN-600 is the worlds first multi-element-reflector radio telescope without any structure linking the surface elements.
The functions normally performed by such structure are instead, executed by the Earth’s rotation.
It can make radio frequency observations in the frequency band ranging from 610 MHz to 30 GHz.
This is especially useful when scanning for variable sources of radiation.
The telescope has also contributed to radio observation for the SETI project.
(SeeThe Arecibo Observatory).
RATAN-600 was built in 1968 and it started operating in 1974.
The biggest part of the telescope are the rectangular reflecting elements.
