The Westerbork Synthesis Radio Telescope (WSRT) is an aperture synthesis interferometer that consists of a linear array of 14 antennas arranged on a 2.7 km East-West line near Westerbork, in the North Eastern Netherlands. It has a similar arrangement to other radio telescopes such as the One-Mile Telescope and the Ryle Telescope. Ten of the telescopes are on fixed mountings while the remaining four dishes are movable along two rail tracks. The telescope was completed in 1970.
The telescopes in the array can operate at several frequencies between 330 MHz and 8.3 GHz. The WSRT is often combined with other telescopes around the world to perform Very Long Baseline Interferometry (VLBI) observations. The telescope is operated by Astron, the Dutch foundation for astronomy research.
