摘　　要： 合成孔径雷达(Synthetic Aperture Radar,SAR)是一种微波的成像系统,具有全天时、全天候观测以及多频段、多极化和多视角等优点。本文在收集各类星载SAR影像数据基础上,通过对空间数据库和空间数据引擎技术的分析,在ArcGIS Engine和.NET的核心语言C#编程环境下,构建了基于Oracle和ArcSDE集成技术的SAR影像库系统。SAR影像库系统实现了影像数据之间的有效存储,以及元数据与影像数据的高效、统一存储,并为典型地物的特征信息提取和判读工具的形成提供了一个高效平台。 Synthetic Aperture Radar is a kind of microwave imaging system with advantages of all day long and all weather observation,multi-frequency band,multi-polarization and multiple points of view,etc.At present,in view of the typical feature analysis of SAR image library system research,this paper collects all kinds of satellite-borne SAR image data,analyses the space database and spatial data engine technology to construct the SAR image library system based on Oracle and ArcSDE integration technology according to the ArcGIS Engine and.net core language C# programming environment.SAR image library system realizes the effective storage between image data and highly efficient storage between meta data and image data,and provides an efficient platform for extract and interpret the typical feature information.
