The paper presents a new processing algorithm for spotlight SAR data processing. The algorithm performs the range cell mnigration correction for non-chirped raw data without interpolation by using a novel frequecy scaling operation. The azimuth processing is based on a spectral analysis approach wich is made highly accurate by azimuth scaling. In almost all processing stages, a subaperture approach is introduced. The paper presents the complete derivation of the algorithm. Processing results using data from the E-SAR-System of DLR are presented.
