Next Generation SAR - External Calibration.

ESA has the intention to develop improved SAR instruments for the post ENVISAT/ASAR era. The so-called Next Genersation SAR will be a high resolution, multi-frequency and fully polarimetric radar with flexible viewing geometry. In response to an ESA ITT a consortium under the leadership of DORNIER is developing different desing options for such a system. Our contribution comprises the external radiometric calibration of the Next Generation SAR.
