Multi-frequency and multi-polarization SAR system analysis with simulation software developed at CSA

The multi-frequency and multi-polarization SAR simulator developed at the Canadian Space Agency (CSA) is aimed to study an advanced SAR system performance in the simulated SAR images. This simulator is designed either as a SAR system simulator which concentrates on the radar system and SAR processing techniques, or as a SAR image product simulator which focuses on a target model and a radar backscattering model, so as to understand SAR polarization characteristics completely. The paper presents the simulation approach of a point target model and a distributed target model for spaceborne SAR which is adopted in the authors´ simulator. The current results are given and the status of the SAR simulator software is addressed
