|The Sardinia Radio Telescope (SRT)
|Sardinia Radio Telescope|
The Sardinia Radio Telescope is a recently completed (2011) radio telescope based in Pranu Sanguni, near Sant'Andrea Frius and San Basilio, about 35 km north of Cagliari (Sardinia, Italy).
The 64-m primary reflector will has an active surface
made of 1008 aluminium panels (RMS ≤ 65 μm) moved by
1116 actuators. The active surface is essential for
observations at high frequencies (23 to 100 GHz). The most
important feature of the SRT is, in fact, its extreme
frequency agility: it is able to observe from 300 MHz
to 100 GHz and can easily swap receivers (20 in total can
be in principle installed on the three focal positions and
be positioned 11 to 190 s).

The receivers commissioned for the telescope first light are:
Pulsar backends: The SRT is using a dual-band digital filterbank (DFB4) from ATNF and a 2 x 1024 x 0.5 MHz filterbank.
- Primary focus: dual L (1.3-1.8 GHz) P (305-425 MHz) band coaxial;
- Gregorian focus: K band multibeam (18-26 GHz);
- BWG focus: C band (5.7-7.7 GHz);
