Abstract

Polarimetric calibration is essential in order to achieve an accurate image interpretation and should be the first step to carry out once we get the full polarimetric data. Hence, a polarimetric calibration tool based on the algorithm proposed by Quegan has been developed and analyzed with data coming from TerraSAR-X and INTASAR RIX prototype. The final aim of this work is to obtain a ready to use polarimetric calibration software not only for these sensors but also for the future earth observation satellite PAZ. The results obtained are analyzed for both sensors. The tool seems to have good performance for TerraSAR-X data and is less effective for the INTASAR RIX prototype data.
