Large reflector antennas, as those used in radio astronomy and deep-space communication, generally are composed of a set of surface panels, supported on three or more adjustable points by a support structure, called the backup structure. After assembly of the reflector it is necessary to accurately locate the panels onto the prescribed surface in order to obtain the maximum antenna gain. The fact that some antennas have a “shaped” contour is irrelevant for the purpose of our discussion. We are concerned with describing a method which allows us to derive the position of the individual panels in space and compute the necessary adjustments of their support points to obtain a continuous surface of a certain prescribed shape.
