- Abstract
Interferometric synthetic aperture radar (InSAR) technology characterized by high monitoring precision, large scale and continuous spatial coverage, has become a powerful means to solve the problems of deformation monitoring in water conservancy projects. To circumvent the difficulties of InSAR time se- ries analysis in deformation monitoring of reservoirs, a systematic research of methodologies and applica- tions is carried out in this paper, considering the complexity and particularity of the application environ- ment. Results from the application in the Guangnan Reservoir reveal that high -precision deformation time series can be extracted, which verifies that it is effective in deformation monitoring of reservoirs through In- SAR time series analysis. Time series InSAR technique has great potential for reservoir safety survey and retrospect of deformation history.
