Abstract : The state of the art of both airborne and space-borne SAR systems with polarimetric interferometry capability, their technological, system technical and application related specifications, and recent results obtained as well are presented shortly with respect to there relevance for Polarimetry and Interferometry capabilities. Space-borne SAR Interferometry in two pass mode reaches altitude accuracies of about 10 m and in one pass mode of 6 m. With differential interferometry accuracies in the cm range have been obtained. In order to reach these values an exact system calibration is indispensable. The calibration of space-borne systems will be discussed using SRTM as an example. The future development of space-borne systems will be discussed shortly also.
