Abstract :
The Microwave Radiometer Instrument (MWR) selected for the ENVISAT-1 mission of the European Space Agency, is a two channel passive radiometer operating at 23.9 GHz and 36.5 GHz based on the Dicke principle. By receiving and analysing the Earth´s generated and reflected radiation at these two frequencies the instrument will measured the amount of water content in the atmosphere within a 20 km diameter field of view immediately beneath the ENVISAT-1 track, this information will allow the correction of atmospheric propagation data for the elaboration of measurements undertaken by the Radar Altimeter 2
