摘要
合成孔径雷达干涉测量技术(InSAR)是以复数据提取的相位信息为源获取地表三维信息,与传统的获取数字高程模型的方法相比,InSAR技术在获取DEM方面具有全天候、大范围、高精度等优势。详细介绍了基于InSAR的DEM获取数据处理流程及方法。
The technology of the InSAR makes use of the phase information extracted from the complex data as the data source to obtain the information of the three-dimensional terrain.Compared with the traditional method for obtaining DEM,the InSAR technology has the advantages of the all-weather,large range,and high-precision in obtaining DEM.This Paper introduces the DEM-obtained data processing flow and method based on InSAR.
