摘要
详细介绍了专业的雷达数据处理软件GAMMA和基于GAMMA的双轨D-InSAR数据处理流程;对济宁地区真实L波段的ALOS PALSAR数据进行了双轨D-InSAR处理,完成了从干涉数据的读取到形变图生成的整个流程,并生成了一系列清晰的结果图;结合GIS软件得到研究区的沉降位置、分布和沉降量等信息。研究表明:利用GAMMA软件可以对雷达影像进行双轨D-InSAR处理,得到清晰的中间结果图;双轨D-InSAR可以对矿区进行地面沉降监测,进而掌握由于煤矿开采引起的地面沉降分布和沉降程度,为煤矿区的合理开采和可持续发展提供一定的理论依据。
The professional radar data processing software GAMMA is introduced in some detail and the data processing flow of two-pass differential interferometry synthetic aperture radar based on GAMMA is described. The L-land ALOS PALSAR images of Jining are processed using the two-pass D-InSAR, the whole process of reag from interferometric images to subsidence map are completed, and a series of clear results are generated;the GIS is used to analyze the ground subsidence, distribution and settlement of the test area. The results show that the two-pass D-InSAR can be processed based on GAMMA software and be used to monitor the subsidence of mine area, thus a theoretical basis for the rational exploitation of mining area and sustainable development are provided.
