Pau-synthetic aperture: a new instrument to test potential improvements for future interferometric radiometers

The Soil Moisture and Ocean Salinity (SMOS) mission is an Earth Explorer Opportunity mission from the European Space Agency (ESA). It was a direct response to the global observations of soil moisture and ocean salinity. Its goal is to produce global of these parameters using a dual-polarization L-ba...

description The Soil Moisture and Ocean Salinity (SMOS) mission is an Earth Explorer Opportunity mission from the European Space Agency (ESA). It was a direct response to the global observations of soil moisture and ocean salinity. Its goal is to produce global of these parameters using a dual-polarization L-band interferometric radiometer the Microwave Imaging Radiometer by Aperture Synthesis (MIRAS). This instrument is a new polarimetric two-dimensional (2-D) Y-shaped synthetic aperture interferometric radiometer based on the techniques used in radio-astronomy to obtain high resolution avoiding large antenna structures. MIRAS measures remotely the brightness temperature (TB) emitted by the Earth's surface, which is not isotropic, since it depends on the incidence angle and polarization, the Soil Moisture (SM) or the Sea Surface (SSS), the surface roughness etc. among others. The scope of this doctoral thesis is the study of some potential improvements could eventually be implemented in future interferometric radiometers. To validate improvements a ground-based instrument concept demonstrator the Passive Advanced Unit Synthetic Aperture or (PAU-SA) has being designed and implemented.
