利用GPS与CRInSAR融合开展微量形变监测的应用研究

Application Research on Micro-Deformation Monitoring Using Fusion of GPS and CRInSAR

利用一种GPS、角反射器和InSAR相融合的微量形变监测方法,在树坪滑坡形变监测中进行了初步应用。利用该方法得到的微量形变监测结果与GPS实测值之间差值的均值为3.33mm,RMS为3.16mm。这一结果表明,利用该方法开展微量形变监测是可行的。

A micro-deformation monitoring method using a fusion of GPS, corner reflector and InSAR, is applied in Shuping landslide deformation monitoring. The mean difference between the deformation monitoring results obtained by the proposed method and measured GPS value is 3.33 mm, and RMS is 3.16 mm. These results show that using this method is feasible for micro-deformation monitoring.
