摘　　要：合成孔径雷达差分干涉测量(D-InSAR)作为一种新型的空间测量技术,具有不受时间和空间的限制、对地物有一定的穿透性等传统测量所不可比拟的特点,作者在介绍其原理的基础上,利用差分干涉测量技术对姚桥矿区进行了变形监测,分析了不能产生明显干涉条纹的原因,并将实测水准数据和利用D-InsSAR技术得到的沉陷值相比较,进行了初步的精度评定.As a new space geodetic technique, differential synthetic aperture radar interferometry （D-In-SAR） have more advantages than traditional geodetic technique such as all-weather, 24-hour continues surveying and ability to penetrate into substances on the earth. This article introduces the deformation monitoring of YAO QIAO with D-InSAR technology at the basic of explaining the principle of D-InSAR. The cause of few obvious interferometric fringes was analyzed. The precision of the observing data was then assessed compared with the ground-based leveling data, and the initial accuracy assessment is done.
