摘要
摘要:地基差分干涉雷达在形变监测领域已经得到了广泛的应用。该文首先概述了地基差分干涉雷达的主要类型，分为地基实孔径雷达和地基合成孔径雷达两类，并选择代表性系统介绍了工作原理及重要参数。然后以地基合成孔径雷达为例，介绍了现阶段差分干涉处理中的重要技术，包括差分干涉、PS点选择、大气相位补偿等。最后以3个应用实例，展现了地基差分干涉雷达，在露天开采边坡监测、山体滑坡监测和桥梁振动测量方面的应用。

Abstract:Ground-Based Differential Interferometric Radars (GB-DInRads) have been widely applied to measure deformations. In this paper, the main types of GB-DInRads are summarized, including ground-based real aperture radar and Ground-Based Synthetic Aperture Radar (GB-SAR). The working principles and important parameters of some representative systems are introduced. Then, taking the GB-SAR as an example, the current key processing techniques are introduced, which mainly include differential interferometry, permanent scatterer selection, and atmospheric phase compensation. Lastly, three examples are presented to show the applications of GB-DInRad in deformation measurements. A Multiple-Input Multiple-Output (MIMO) radar was utilized to monitor an open-pit mine for about 11 days, and two regions with obvious deformation were found. In addition, a linear-scanning GB-SAR was utilized to monitor a mountain slope after severe landslide. The analysis result proved that rainfall could accelerate deformation. The feasibility of vibration measurement with the MIMO radar was also discussed in this paper.
