雷达地杂波特性与相对应的具体地形起伏和地物特征息息相关,将二者以数据库的形式相结合,这对于地杂波特性的分析、研究和应用带来很大的便利。文中主要研究机载雷达杂波和三维可视化地理信息系统(G IS)结合技术,并建立基于G IS杂波特性应用数据库。该数据库无论是从数据的组织结构和库的建立,还是从面向实际应用分析的方面来说,都比传统的杂波数据库有了较大的改进和提高。

The characteristics of the ground clutter is closely related with the corresponding terrain.It is quite convenient for the study and application of the characteristics of ground clutter to combine it with the terrain characteristics by using a database.In this paper,the technique of combining airborne radar clutter with three-dimensional geographic information system is studied.Furthermore,the application database of clutter is constructed.Compared with traditional clutter database,the data organization and database construction as well as its application are improved greatly.
