Abstract :
The differential InSAR techquque with corner reflectors(CR-InSAR) may be more effective than the conventional D-InSAR. 18 artificial trihedral triangle corner reflectors are set up in the Yanhui basin and its edge area to study the small crustal deformation there. The CRs are bright color targets in SAR intensity image and their Radar Cross Section (RCS) was be calculated. On this basis, this thesis obtained the subtle deformation in the testing area by using CRInSAR. The deformation at CR points is dominated by LOS (line of sight) decline at -2.0mm/yr~0.0mm/yr during 2004~2008.
