(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.
