大气扰动误差作为地基 InSAR 测量中的一个重要误差源,其引起的干扰不可忽视, 本文以滑坡监测区域为研究对象,基于 IBIS-L 系统获取到的监测区数据,根据热信噪比、估计信噪比、空间相关系数和相位稳定性等特性,选取监测区域内稳定的 GCP 对观测目标中的大气扰动误差进行改正, 实验结果表明,GCP 方法能有效削弱地基 InSAR 测量中的大气扰动影响,提高观测的精度,

Atmospheric disturbance error is one of the major factors in ground-based interferometric synthetic aperture rader （GB- InSAR）, and the interference caused by it can′t be ignored. In this paper, the monitoring area of the landslide is taken as the researchobject, according to the characteristics of the thermal signal to noise ratio, the estimation of the signal to noise ratio, the spatial coherence and the phase stability in the data obtained from the monitoring area based on the IBIS-L system, stable GCPs in the monitoringarea are selected ...
