Ukrainian T-shaped Radio telescope, second modification
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 built in the early 1970s near the village of Grakovo (49°38′N 36°56′E), 65 km south-east from Kharkov, Soviet Union
. The telescope is operated by the Institute of Radio Astronomy of the Ukrainian Academy of Sciences.
The UTR-2 comprises 2040 array elements in two arms: north-south (1800×60 m) and west-east (900×60 m). It has the collective area of 150000 square metres (1,614,586.6 sq ft), and the resolution about 40'×40' (12×12 m) 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 Soviet decametric VLBI system URAN, which included another four radio telescopes of smaller size. The system has bases from 40 to 900 km (25 to 960 mi).
