GPS -InSAR合成方法用于地面沉降监测的可行性展望

GPS技术在地面沉降领域的应用已日臻成熟并完善；InSAR技术在地面沉降领域的应用已经开始但还未成熟，目前是研究热点。GPS—InSAR合成方法是将GPS高时间分辨率和InSAR高空间分辨率进行有效的统一，使两种技术达到互补，从而发挥各自的优势。本文指出了GPS—InSAR合成方法用于地面沉降监测的可行性，并对两种实施方案进行了探讨。最后对西安地区开展GPS—InSAR研究进行了展望。

Prospect of GPS-InSAR Integration of Research into land subsidence

Using GPS for the monitering of land subsidence is efficient,and using InSAR for it has already started but is immature,using InSAR for land subsidence monitering is a houspot.Integration of GPS and InSAR is to carry out unification of GPS high temporal resolution characteristic and InSAR high spatial resolution characteristic,to complement each other.This paper indicates the feasibility of integration of GPS and InSAR for land subsidence monitering,and then discusses two projects to implement,and the prospect of GPS-InSAR at finally.
