Abstract

Compact Antenna Test-Ranges (CATR) represent a highstandard of state-of-the-art test facilities with a fast and realtime measurement capability up to the sub-millimeter range. Futurescientific observation instruments of ESA such as the Planck andHerschel telescopes are working within this frequency ranges and require a high measurement accuracy for large antenna apertures. This present paper shows the first modelling of a large CATR atmillimetre frequency. The software used in this paper is GRASP8(from TICRA), and specially the recent Multi-ReflectorGeometrical Theory of Diffraction upgrade (MR-GTD thereafter).
