Interferometry technique

Aperture Synthesis

The technique, developed by Martin Ryle, of building up an image from an interferometer by combining measurements taken as the Earth's rotation carries the antennas to different orientations — synthesising the resolution of a single huge aperture from many small ones. The basis of modern radio imaging.
