Aperture Synthesis

(Synthesis Imaging)
(interferometry to simulate a larger aperture telescope)

Aperture Synthesis (Synthesis Imaging) is a method of using an Interferometer to produce an image with an Angular Resolution as would be provided by a single Aperture as wide as the baseline length. It is used for Visible Light, Infrared, Microwave, and Radio astronomy.

As far as I can tell, the typical arrays of two or more telescopes (e.g., multiple Radio Telescope dishes) labeled interferometers are intended to produce a high angular resolution and it would seem the term aperture synthesis applies to all them.
