Abstract :
Next generation Synthetic Aperture Radar (SAR) spaceborne sensors are being deployed with different acquisition modes including Scanning SAR (ScanSAR). That is due to the wider swath that ScanSAR provides. In this frame, this paper takes some known SAR processing techniques and studies their application to ScanSAR raw data processing. The methods based on Spectral Analysis (SPECAN) are convenient to treat ScanSAR data due to their burst processing capability in comparison with other methods designed for Standard high precision products. In this work, a careful study about special features of ScanSAR data is carried out. Then, a technique is selected and evaluated using a simulation environment.
