Abstract

In order to make the best use of the data produced by the KOMPSAT-5 (K5) Synthetic Aperture Radar (SAR), there is the need to perform a continuous process of calibration during the operational lifetime of the system, based on data acquired over targets of known characteristics with supporting data provided by the instrument itself. The main aim of the Radiometric Calibration process is to relate the pixel intensity in the imagery output by the SAR processor to the radar cross-section on the ground.
