| Abstract: | Artificial corner reflector(CR) point is so strong scattering and has stably reflected phase in SAR images that it helps to overcome the limiting factors of coherence in the application of traditional InSAR.At present,the CR-InSAR based on CR points has been used to study the deformation of some areas with complex terrain.We introduce the experiment for CR’s installation and identification in the Xianshuihe and Longmenshan fault.Based on the GPS measurement assisted to identify the CR points,a new contrasted method is proposed,which uses the magnitude of the average multiple images before and after the CR installed to identify the CR points.This method can determinate the accurate position of the CR point in the image. |
