| Abstract: | As an important supplementary data source for optical satellite to acquire data area,spaceborne SAR image is a means of updating basic geographic information.The imaging mechanism and spectral geometry of SAR image are studied.This paper summarizes the method and process of SAR image processing based on GF-3 satellite,and forms the production technology scheme of DOM products based on SAR image,which provides reference for large-scale production practice. |
