TOPS Sentinel-1 and TerraSAR-X Processor Comparison based on Simulated Data

The paper reports about the comparison of the Sentinel-1 Prototype TOPS Processor with the Experimental TerraSAR-X TOPS processor. The comparison is based on simulated raw data generated from TerraSAR-X and Sentinel-1 parameter scenarios. Fundamental impulse response parameters were investigated in point target scenarios. Scenarios with point targets on top a noise floor allowed for comparison of burst images by means of a cross-interferogram. The comparison shows good accordance between the processing results from both processors.
