苏州地区地面沉降的星载合成孔径雷达差分干涉测量监测
摘要
利用欧洲空间局ERS-1/2获取的苏州地区1993～2000年SAR数据,通过差分干涉测量处理,得到1993～1995,1995～1998和1998～2000年苏州市地面沉降场测量值.地面水准测量数据的验证分析表明,差分干涉测量值与水准测量值的相关度达0.943,标准误差均值为0.1706,雷达差分干涉测量精度可达5mm(以水准测量代表地面形变的真实情况).文中以7个水准测量基准点为例,分析上述3个时段的地面沉降速率,其总体趋势反映苏州市地面沉降速率趋于减缓,说明近年苏州的地面沉降得到了有效的控制.研究结果表明,SAR差分干涉测量技术进行城市地面沉降方面监测和时空演化特征研究具有很大的优势,同时可用于其他类型城市地质灾害的监测.
