|
摘要
合成孔径雷达干涉测量(InSAR)是一种获取矿区数字高程模型(DEM)的新技术。基于煤矿区地表形变的基本特征,在介绍雷达干涉测量高程模型的基础上,叙述了利用InSAR技术建立数字高程模型的方法和过程,并对影响数字高程模型精度的因素进行了定性分析。
Interferometric synthetic aperture radar(InSAR) has been used as an innovative technique for digital elevation model (DEM) generation.This paper investigates the methods and process of DEM generation through InSAR,based on basic character of the ground deformation in coal mine area and a brief introduction of elevation model generation through radar interferometry,and gives a qualitqative analysis on factors affecting the accuracy of DEM.
