摘要
收集了1992年12月至1998年6月JERS-1L波段雷达数据,利用差分雷达干涉测量技术进行地面沉降监测研究。通过"二轨法"进行差分处理,选择其中的6景差分雷达干涉图进行分析。在研究区内发现了4个沉降区域,并按照时间序列通过对地面形变图进行分析,获取其中两个沉降区最大的垂直沉降量。
In this study, two-pass differential InSAR technique was used to monitor ground subsidence. JERS-1 L-band SAR imagery, acquired from December 1992 to May 1998, was selected as experimental data. 6 interferometric pairs were selected, and 4 subsidence bowls were found in the research area. Based on the temporal series of height change map, maximal vertical subsidence rate of two bowls was obtained. The studies show that DInSAR technique has great potential in ground subsidence monitoring.
