Abstract
For spaceborne ScanSAR system, the wide swath is the advantage whereas it induce some problems. In this thesis the importance of accurate geometry model for ScanSAR simulation is fully analyzed. A SAR geometry model based on valid coordinate systems is proposed. It provides actual phase history and echo not only for ScanSAR but also traditional SAR system. The simulation shows that it is effective and practical.
