Geohazard Supersites and Natural Laboratories

The SSC product is a single look product of the focused radar signal. The pixels are spaced equidistant in azimuth (according to the pulse repetition interval PRI=1/PRF) and in slant range (according to the range sampling frequency). The data are represented as complex numbers containing amplitude and phase information. Each image pixel is processed to zero Doppler coordinates in range direction, i.e. perpendicular to the flight track. Due to the nature of azimuth/slantrange coordinates, no geocoding is available. The SSC is delivered in the DLR-defined binary COSAR format (see TerraSAR-X Level1B Product Format Specification). The product is compatible with the standard slant range products (SLC) available from ERS-1/2, ENVISAT ASAR, RADARSAT-1 and X-SAR/SIR-C. The SSC product is intended for applications that require the full bandwidth and phase information, e.g. for SAR interferometry and polarimetry. Depending on the required application, this product may be preferred to geocoded data, since it does not include any radiometric artefacts which may be introduced during spatial resampling and geocoding.
