Radiometric Calibration is an essential activity, both on- ground and in-flight, for the correct operations of any Radiometer System. In the frame of M.I.M.R. (Multi-Frequency Imaging Microwave Radiometer) project, Officine Galileo participated from the early phases with system activities relevant to calibration and with development of Calibration devices. In particular the breadboard of the in-flight calibrator during phase B, and the Targets for on-ground radiometric characterization of M.I.M.R. during present Demonstrator phase, were designed, manufactured and tested. This paper describes the two Targets, working at fixed cryogenic temperature (Fixed temperature Target, FT) and at temperature settable from cryogenic to ambient (Variable temperature Target, VT) that have been used for the M.I.M.R. Demonstrator test campaign. Moreover the in-flight calibrator, that was also used in this campaign, is described.
