基于雷达卫星时序分析技术的荆江沿岸堤防形变研究
Detection of Deformation along Jingjiang Segment of Yangtze River Dyke Based on Radar Satellite Time Series Analysis Technique
摘要
Abstract
In this research we collected 32 radar satellite images from 2018 to 2019, and monitored the settlement of Jingjiang segment of Yangtze River dyke segment from Shishou to Jianli using PS-InSAR technology. We obtained the deformation trend and its physical mechanism by analyzing the average settlement rate from April 2018 to April 2019. Results unveiled uneven settlement in this segment of dike; but the deformation trend changes with time in a year. Radar satellite time series analysis technology could highly-effectively monitor the settlement of Jingjiang Riv-er dyke in a large range, which suggest that radar satellite time series analysis has great application potential in the deformation monitoring of the Yangtze River embankment.关键词
