InSAR技术在沂沭断裂带地表形变监测中的应用研究
Research of SAR Interefrometry for Yishu Fault Zoon Surface Deformation Monitoring
摘要
Abstract
Aiming at the limitations of the traditional geodetic measurements in inversing the tectonic stress field completely in the region near Yishu fault zone. Two InSAR time series analysis methods were introduced into the deformation monitoring of the region. The paper firstly derived and analysed the basic principles of SBAS-InSAR technique detailedly. On this basis 14 scenes of ENVISAT-ASAR images covering the area were processed and analysed by using the PS-InSAR and SBAS-InSAR technique the annual average rate of deformation of the area was obtained. The results compared with precise leveling measurements shows that the two methods are of consis-tency in deformation tendency and SBAS-InSAR technology can get a better effectiveness of monitoring with the small amount of data in monitoring the wide range continuous slow fault surface deformation. The research results show that the InSAR time series analysis method can be used as a tools in small surface deformation monitoring of the fault.关键词
