| 摘 要： | 在介绍永久散射体与短基线集雷达干涉测量方法的基础上,以辽宁省盘锦市为例,运用两种方法研究了其市区地表形变特征。对比升降轨永久散射体方法与短基线方法所得到的形变平均速率和时序分析可知,两种方法所得的研究区域的地表形变趋势较为可靠,且以垂直沉降为主,新城区是最大沉降区域,最大下沉速率达20 mm/a,其他区域较为稳定。

| Abstract: | Following a brief introduction to their principles,persistent scatterers(PS) and small baseline(SBAS) InSAR techniques are employed to map surface movements in the Panjin city,China.It is demonstrated that both advanced InSAR techniques provided comparable mean velocity maps and deformation time series,and suggested the new city centre of Panjin exhibited surface subsidence with a mean velocity of up to 20 mm/a during the period between 2003 and 2006. |
