摘要：Synthetic Aperture Radar (SAR) image is not easy to interpretation because of its image unique characters, and there is a close relationship between the Doppler parameter and the quality of SAR image, these factors actually impact the application of SAR image in topographic surveying and mapping, although it is a active sensor and it is less affected by the weather and time. This paper focuses on the impact of the SAR image quality and SAR image interpretation in the application of topographic surveying and mapping, which caused by the low accuracy of SAR Doppler parameter and range migration, and as well as on a more practical way to improve the precise of SAR Doppler parameter with a visualization approach, so a better Doppler parameter can be utilized in topographic surveying and mapping
