基于SBAS-InSAR时序分析技术的兖州矿区沉降监测与分析

Ground Settlement Monitoring and Analysis in Yanzhou Mining Area Based on SBAS-InSAR Time Series Analysis

针对InSAR技术受空间和时间基线的限制,多数情况下难以获得连续沉降场的问题,基于SBAS-InSAR时序分析技术,以兖州矿区为实验区,对2008年1月20日至2010年9月26日C波段的ASAR数据进行处理,获取了兖州矿区的地表形变信息,生成了沉降图及其平均沉降速率图,直观地反映了矿区地面沉降过程,并对结果进行了分析。结果表明,SBAS-InSAR时序分析技术可以有效地解决时空失相干问题,为矿区地表监测提供了可靠的技术支持。

Due to the limitation of space and time baseline for InSAR technology, it is difficult to obtain continuous settlement field in most cases. Processed the C-band ASAR data from January 20,2008 to September 26, 2010 based on the SBAS-InSAR time series analysis technology with the Yanzhou mining area as the experimental area, and obtained the surface deformation information of the Yanzhou mining area, generated the settlement map and its average settlement rate map, which directly reflected the ground settlement process in the mining area and analyzed the results. The results show that SBAS-InSAR time series analysis technology can effectively solve the problem of space-time loss coherence and provide reliable technical support for surface monitoring in mining areas.
