Abstract

Range Doppler Algorithm (RDA) is the first algorithm that has been used to reconstruct the synthetic aperture radar (SAR) image formation. The data can be gathered from both airplane and satellite. Data gathering by satellite is general. The problem with space born data gathering is range cell migration which is generated by the relative motion between satellite and terrain being imaged during data gathering. In this paper we implement the range Doppler algorithm on space born real data gathered from RADARSAT to generate SAR image and compensate the effect of range cell migration.
