In this study synthetic aperture radar (SAR) raw data are analyzed and processed via various processing algorithms. Characterization of the surface reflectivity pattern is performed. Surface reflectivity pattern is obtained by using SAR raw data and transfer function of the system. Two algorithms, namely narrow focusing and wide focusing, are examined for boresight geometry. With the approach used in the study, operation on a certain amount of data set is possible without being have to process the whole data. This is quite advantageous since it provides time efficiency and ability to focus on desired geographical regions. Advantages of this procedure are given and applications to ERS-2 raw data for Istanbul, Turkey are presented. Statistical analysis of the raw data is clearly shown.
