End-to-end Simulator of 2-D Interferometric Radiometry
2003
An end-to-end simulator for the assessment of the performances of a spaceborne
interferometric radiometer measuring the brightness temperature of Earth’s surface
(ground and sea) is presented. The tool covers the complete simulation of the input
brightness temperature map, the full instrument modeling, the instrumental error
correction, and the inversion algorithm to recover the brightness temperature. The output
maps are presented in a graphical format including most of the standard cartographic
projections. The simulator has been developed with two main objectives: (1) to provide
the engineers a tool to predict system performance, and (2) to provide the scientific and
end users a tool to help them in the implementation and improvement of algorithms for the
Soil Moisture and Ocean Salinity (SMOS) retrieval for the SMOS Earth Explorer
Opportunity Mission of the European Space Agency.
