J M Hedgepeth: 1375. Accuracy Potentials for Large Space Antenna Structures. 1980.



Analytical results indicate that a careful selection of materials and truss design, combined with accurate manufacturing techniques, can result in very accurate surfaces for large space antennas. The purpose of this paper is to examine these relationships for various types of structural configurations. Comparisons are made of the accuracy achievable by truss-and dome-type structures for a wide range of diameter and focal length of the antenna and wavelength of the radiated signal.
