MIRAS ground characterization

Abstract

On-ground characterization of the complete microwave imaging radiometer with aperture synthesis (MIRAS), successfully manufactured by EADS-CASA Espacio, is briefly described. The characterization includes (a) Basic functionality tests and internal calibration assessment carried out at the manufacturer premises, (b) Operation under extreme thermal conditions at the ESApsilas Large Space Simulator and (c) Image validation tests at the ESApsilas Maxwell anechoic chamber including also response to point sources. Description of the different tests carried out and detailed results of the instrument characterization including graphics of the different parameters retrieved and images of the empty chamber are provided.
