VLA Expansion Project (EVLA).

NRAO has recently enhanced the capabilities of the Very Large Array (VLA) Radio Telescope.  Find out more about this by visiting the VLA Expansion Project site.

In addition to new electronics in the antennas, a new correlator computer, known as WIDAR, was developed in a joint effort with Dominion Radio Astrophysical Observatory (DRAO).

Here is a nice overview of the WIDAR correlator used to familiarize the VLA Operators.

Here are some raw pictures of the EVLA Correlator System and components taken throughout the life of the project.
