摘要
合成孔径雷达干涉测量(In SAR)是一种快速发展的大地测量技术,能够全天候获取高精度、连续覆盖的地面高程和地表形变信息。In SAR已在地形测绘、全球环境变化、灾害监测评估等相关领域得到了广泛应用并取得了一系列成果。主要综述了近20 a来In SAR技术的发展,以及该技术在数字高程模型提取和地球科学应用中的研究进展,并对该技术的发展趋势及应用研究进行了展望。
As an advanced and rapidly improved geodetic technique,Interferometric Synthetic Aperture Radar（In SAR）can obtain terrain elevation and surface deformation with high precision and continuous coverage in all-weather. At present,In SAR has been widely applied and obtained a series of achievements in the fields such as topographic surveying and mapping,global environmental change,disaster monitoring and evaluating,etc.In this paper,the research progress of development and application of In SAR technology during the past 20 years was mainly summarized. And the development trend and application study were prospected.
