Since November 2006, DLR operates F-SAR - a new airborne SAR sensor beside its experimental airborne SAR sensor E-SAR. F-SAR is a totally new development utilizing most modern hardware. It is presently operated in X-band and has been supplemented recently being fully polarimetric. F-SAR already accomplished several flights and acquired SAR data in different operation modes, amongst others in along-track-interferometric and full polarimetric mode. Several data takes were acquired at the Kaufbeuren calibration site where eleven permanently deployed corner reflectors are used for calibration. The paper describes the X-band subsystem calibration of F-SAR in geometric, radiometric and polarimetric terms and for along-track interferometry.
