Abstract :
This paper describes measurements done to verificate and to test the performance of two methods used to calibrate fringe-washing effects occurring with large aperture synthesis radiometers. The methods tested in the paper are the ones proposed for the fringe-washing calibration of the MIRAS instrument of European Space Agency´s SMOS mission
