Extended chirp scaling algorithm for air- and spaceborne SAR data processing in stripmap and ScanSAR imaging modes

Abstract

AbstructThis paper presents a generalized formulation of the extended chirp scaling (ECS) approach for high precision processing of airand spaceborne SAR data. Based on the original chirp scaling function, the ECS algorithm incorporates a new azimuth scaling function and a subaperture approach, which allow an effective phase-preserving processing of ScanSAR… (More)
