摘　　要：阐述了合成孔径雷达干涉测量技术在地震监测方面的历史及现状;指出了"三轨"差分的基本原理;利用ENVISAT数据获取了巴姆地震形变场,并对地震形变结果进行了解译。发现形变主要发生在东面南北方向,南面地表上升约30cm,北面地表下降约18cm。The history and actuality using differential synthetic aperture radar interferometry （D-InSAR） to monitor earthquake are described in brief. The principles of ＂two-pass＂ and ＂three-pass＂ are discussed. The deformation filed of BAM earthquake was obtained by ENVISAT data, and the deformation results of the earthquake were analyzed. The conclusion is that the deformation mainly happened in the North-South of the East, and the surface of the South rose about 30cm, while that of the North descended about 18cm.
