Paper Abstract
In order to monitor the surface deformation of Shuping landslide in the Yangtze River Three Gorges area, the method of
differential SAR interferometry (DInSAR) using corner reflectors (CR) was applied. 12 CR, including 10 pyramidal
corner reflectors (PCR) and 2 asymmetrical cubic corner reflectors (ACCR), were designed, made, and deployed on
Shuping landslide. Based on the numerical test and the preliminary analyses of 5 ENVISAT ASAR images, we
concluded that: 1) ACCR can provide strong response signal even without the best SAR look angle and is especially fit
for the multi-angle applications of DInSAR; 2) given a simple phase model, the least square (LS) method can be used to
analyze the CR's differential phase and get the accumulative deformation value.
