Success Criteria Tool in EMC Tests for Interferometric Radiometers

The Microwave Imaging Radiometer using Aperture Synthesis (MIRAS) is the single payload of the SMOS (Soil Moisture and Ocean Salinity) mission by the European Space Agency (ESA) to be launched by spring 2009. This work presents the success criteria tool that has been designed to easily assess the impact of any perturbation on the payload system performance. The tool is illustrated by showing some of the main results obtained during the MIRAS system performance tests by the prime contractor, EADS-CASA Espacio, Spain, at ESA premises in ESTEC, The Netherlands, and after payload integration with the Proteus platform at Thales Alenia Space in Cannes, France.
