摘要/Abstract

摘要： 形变监测是在各类大型建筑物倒塌、桥梁垮塌、滑坡等灾害事故发生前进行预警的重要手段。地基合成孔径雷达干涉测量技术在形变监测的各类方法中，优势明显并已经得到广泛应用。针对现在GB-SAR只能测量目标一维形变的问题，本文提出了一种平行合成孔径雷达的概念，通过在多孔径干涉技术得到的二维位移基础上，融合平行雷达监测的目标位移数据，准确演算得到目标的三维位移信息，从而反映出目标的真实位移，对于建筑物结构性能的监测和诊断具有重要意义。

Abstract: Deformation monitoring is an important way of early warning before the calamity accidents happen, such as variouslarge-scale building collapse, bridge collapse, landslide and others. Ground-based interferometric synthetic aperture radar has obvious advantages and been widely used in various methods of deformation monitoring. Aiming at the problem that GB-SAR can only measure one-dimensional deformation of targets, the concept of parallel synthetic aperture radar is proposed. Based on the two-dimensional displacement obtained by multi-aperture interferometry and integrated the target displacement date monitored by parallel radar, the three-dimensional displacement information of the target is obtained by accurately calculation, which can reflect the real displacement of target, which is of great significance for the monitoring and diagnosis of the structural performance of the building.

Key words: ground-based synthetic aperture radar, health monitoring, multi-aperture interference, parallel radar, three-dimensional displacement
