摘要: The L-band Microwave Imaging Radiometer with Aperture Synthesis (MIRAS), scheduled to be flown as single payload on board the European Soil Moisture and Ocean Salinity (SMOS) mission, has a very wide field of view synthesizes narrow beams by means two-dimensional (2-D) interferometry, same concept used in radio astronomy. Wide is indeed key feature this radiometer, which leads naturally measurement full vector brightness temperatures image. This paper analyzes theory polarimetry 2-D wide-field-of-view microwave interferometry describes way MIRAS will measure polarimetric temperatures.
