Abstract :
This paper describes the simulation of Staring Spotlight as well as Sliding Spotlight distributed target raw data sets from Stripmap raw data, using a time variant bandpass filter. Examples of simulated raw data generated from X-SAR/SRTM Stripmap raw data, are shown for both, Staring as well as Sliding Spotlight modes. The simulated raw data are processed using the TerraSAR-X Spotlight processor. The focused data are compared to the results of the operational X-SAR/SRTM Stripmap processor. Quality analyses of a point target contained within the data, demonstrate the applicability of both, the simulation approach and the TerraSAR-X Spotlight processor
