Interferometer array

Definition

An interferometer array is a network of radio telescopes that work together to observe astronomical objects with higher resolution. By combining the signals from multiple antennas, it effectively simulates a much larger single telescope.

5 Must Know Facts For Your Next Test

1. Interferometer arrays improve angular resolution by increasing the effective aperture size.
2. They use the principle of interference to combine signals from multiple telescopes.
3. The Very Large Array (VLA) in New Mexico is one of the most famous interferometer arrays.
4. Data from each antenna in an array are combined using complex algorithms called correlation.
5. Interferometer arrays can be used to observe various wavelengths, not just radio waves.
