Abstract

This paper presents the first results of a hybrid synthetic aperture interferometric radiometer-GPS reflectometer called Passive Advanced Unit-Synthetic Aperture (PAU-SA). These tests are focused in the PAU-SA\´s performance with preliminary results at baseline level in order to characterize the radiometer part. The tests performed are: characterization of the radiometer noise and its stability through "Allan\´s variance", radiometric sensitivity, calibration of the offset errors and baseline response to a point source at different angles and polarizations.
