摘要
为了研究昆明市长水国际机场及其周边区域的地表形变,本实验利用永久散射体干涉技术(Permanent Scatterers InSAR,PS-InSAR)和37景Sentinel-1数据,并通过GIS方法绘制形变场,得到了研究区2015年至2017年间的地表沉降信息。实验结果发现,研究区域内普遍存在速率在mm/a之间的微小形变,但并未发现明显的高速率形变场。
To study the deformationphenomenon around Kunming Changshui International airport,PS-InSAR techniqueand 37 descending images from the Sentinel-1 have been applied. The deformationzone was revealed via GIS,and the subsidence information from the year 2015 to 2017 was extracted. The result showed that there was extensive and smalldeformation around Changshui airport,whose subsidence ratedamong mm/a,but no large-scale deformationareas with rapid rate were found. Key words： permanent scatterers; InSAR（ PS-InSAR）; Sentinel-1; Kunming Changshui International Airport; ground deformation
