Surface error correction of a mesh deployable reflector

Abstract. Large Deployable Reflector (LDR) systems are commonly used as mesh reflectors for large aperture space antennas in aerospace applications since they provide affordability while guaranteeing at the same time a high gain and directivity. To improve surface accuracy several methods have been studied, most of which measure distance between cable-net system that forms reflector desired paraboloid. In this paper we want to reflector’s ability convey greater concentration reflected rays direction feed. deal with issue, numerical optimization algorithm has proposed.
