利用航天飞机成象雷达干涉数据提取数字高程模型
中国科学院遥感应用研究所,北京100101
摘要:

首先介绍干涉雷达(INSAR)成象原理和处理方法,接着介绍了二维离散包缠(wrapped)干涉相位纹图的解缠(unwrapping)算法。利用航天飞机成象雷达(SIR-C)1994年10月获取的昆仑山干涉数据,研究了SIR-CINSAR获取数字高程模型的方法,显示了INSAR在三维信息获取和动态监测方面的优越性和应用前景。

Using SIR-C Interferometric Data for DEM Acquisition
Abstract:

The Spaceborne Image Radar (SIR-C) onboard the space shuttle Endeavor acquired interferometric synthetic aperture radar (INSAR) data over Mt Kunlun,NW China,during its second flight In this paper,DEM acquisition of test site using SIR-C INSAR data was demonstrated The main procedure included coregistration of data,remove of flat terrain effect and phase unwrapping using DCT technique The results show more details than the existing topographic map The precise correction and analysis have to be done in the further work.

Key Words:

INSAR  SIR-C  DEM
