Ukrainian T-shaped Radio telescope, second modification

From Wikipedia, the free encyclopedia

The Ukrainian T-shaped Radio telescope, second modification (official abbreviation UTR-2) is the world's largest radio telescope at decametre wavelengths. It was build in the early 1970's near the village of Rakovo ( 50°52′N 36°08′E), 40 km West-North from Belgorod, Russia. The telescope is operated by the Institute of Radio Astronomy of the Ukrainian Academy of Sciences.

The UTR-2 comprises of 2040 array elements in two arms: North-South (1800m x 60m) and West-East (900m x 60m). It has the collective area of 150 000 m², and the resolution about 40'x40' at the middle frequency 16.7 MHz. The operating frequency range is 8-40 MHz. The sensitivity is about 10 Jy.

The telescope is a part of the Ukrainian decametric VLBI system URAN, which includes another four radio telescopes of smaller size. The system has bases from 40 km to 900 km.
