It is operated on a Dornier Do-228 aircraft from altitudes of 2000 to 6000 m above ground in X-band (3 cm wavelength) only, featuring four transmit (operated sequentially) and twelve parallel receive channels. Depending on antenna deployment, it is either fully polarimetric (HH,HV,VV,VH), inetrferomtric in along- and/or across-track mode, or can be operated as a digital beamforming SAR. It has full repeat-pass capabilities. Data are processed up to three different levels: RGI (Radar Geometry Image product), INF (Interferometric product) and GTC (Geocoded and Terrain-Corrected product). The data acquisition modes are selected based on the individually planned experiments. Achieved resolutions are presently 10 cm in azimuth and 17 cm in range but will go down significantly below 10 cm in both directions.

November 2010 zur Durchführung der Richtlinie 2007/2/EG des Europäischen Parlaments und des Rates hinsichtlich der Interoperabilität von Geodatensätzen und -diensten 2010-12-08 See the referenced specification true The RGI products are derived from RAW data acquired by the SAR sensor. INF and GTC products are based on the respective RGI product. All data processing is performed by DLR-HR proprietary software, i.e. the SAR Technology Experimental Processor STEP. SAR data are calibrated and motion compensated based on precise antenna measurements from DLR-HR’s CTR facility using as input also DEM information.
