          Abstract

          An approach for simulation and analysis on the high resolution Synthetic Aperture Radar (SAR) images is provided and bridges are chosen for analysis. According to the principle of SAR, the Geometry Optics (GO) is employed to calculate the direct scatterings and multi-path scatterings of the bridge in this approach. In this study, the Sydney Bridge is chosen for analysis, and the Terra-SAR data with 1 m resolution is used. The results show that, the main properties of the bridge with the simulation and the real data are consistent, which tests the validity of the approach. Furthermore, according to the simulation process, the main scattering characteristics of the SAR image of the Sydney Bridge are interpreted. The experiments show that this approach can provide the main scattering characteristics of the target, and also show that it can be helpful for SAR images interpretations.
