Abstract
In this paper a processing algorithm for sliding spotlight SAR raw data with consideration of orbit geometry is presented. The processing is based on the chirp scaling algorithm with a pre-processing step for the sliding spotlight mode. The chirp scaling processing algorithm for SAR raw data assumes a flat Earth geometry. This approximation is not valid for a high resolution satellite Proposed algorithm considers a circular orbit and corrects the processing algorithm accordingly through a range dependent velocity ratio. The processing algorithm is evaluated on a simulated raw data of a scene consisting of ideal point targets.
