Interferometry technique

Radio Interferometry

Linking many radio dishes so that they act together as one telescope as large as their separation, giving radio astronomy its sharpest images. Arrays like the VLA and ALMA correlate the signals from every pair of antennas to reconstruct the sky.

Highlights

  • Many dishes acting as one telescope the size of their spread
