摘　　要：将星载SAR影像作为光学卫星难以获取数据地区的重要补充数据源,是基础地理信息更新的一种手段。通过对SAR影像成像机理、光谱几何特征等进行研究,总结基于高分三号卫星SAR影像处理的方法和流程,形成星载SAR影像制作DOM产品的生产技术方案,为大规模开展生产实践提供借鉴。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.
