基于时序InSAR技术的信阳市中心城区地面沉降监测
Land Subsidence Monitoring in the Central Urban Area of Xinyang City Based on Time-Series InSAR Technology
摘要
Abstract
Based on the Small Baseline Subset Interferometric Synthetic Aperture Radar(SBAS-InSAR)to process Sentinel-1 satellite data from November 2018 to October 2022,which obtained the cumulative land subsidence in the central urban area of Xinyang.The Permanent Scatterer InSAR(PS-InSAR)was used to verify the homonymous points in the settlement area.The results showed that the settlement results of PS-InSAR and SBAS-InSAR maintained good consistency.The overall urban area of Xinyang City Center exhibited the characteristics of"stable old city,subsidence new area",with Yangshan New Area having the most obvious surface subsidence.The use of SBAS-InSAR technology for urban subsidence monitoring has certain applicability and reliability,which can provide the reference for future monitoring and early warning of surface subsidence in the central urban area of Xinyang.关键词
