A survey is given of the multifrequency imaging microwave radiometer based on the work and advice of the instrument panel group, and the results of the industrial activities performed within the framework of the Earth Observation Preparatory Programme (EOPP). The microwave radiometer history on spacecraft is tabulated. The mission objectives and measurement requirements are defined. The MIMR (Multifrequency Imaging Microwave Radiometer) was studied in a prefeasibility study, in order to establish the foundation of a design based on parametric tradeoff. A brief survey of radiometer calibration problems is presented. On the polar platforms and over oceans, MIMR data will be very useful, in particular for studies of heat exchange across the air sea surface.
