摘要
差分合成孔径雷达干涉测量是近几年迅速发展起来的微波遥感技术,具有高分辨率、全天时、全天候、大区域等突出优势,已经成功应用在城市的地面沉降监测中。分析差分干涉测量的整个处理流程,应用GAMMA软件实现了美国某地区雷达影像的差分干涉处理,精度达到厘米级甚至毫米级。验证了D-InSAR技术可以成功应用于城市地面沉降的监测,为预防地面沉降的危害提供了研究依据。
In recent years,Differential Interferometric Synthetic Aperture Radar（D-InSAR） is the rapid development technology in the microwave remote sensing with high precision, all-time, all-weather and large regional imaging capabilities. It has been successfully applied in the city＇s land subsidence monitoring by its unique advantages. This paper introduces D-InSAR processing procedure. It can be Monitoring of ground deformations in USA with GAMMA. the result shows that the precision is in centimeter （even in millimeter） level. Thus, It validates the conclusion that D-InSAR technology could be successfully applied to the city＇s landsubsidence monitoring, and provides the research basis for the prevention of the city land subsidence damage.
