| Abstract: | As using corner reflector-synthetic aperture radar interferometry(CR-InSAR) to monitor surface deformation,the integer parts of observed phase are lost.In order to obtain the integrated phase of deformation,it is necessary to unwrap phase.This paper studied the phase unwrapping problem of CR-InSAR,and made tests to apply the least squares ambiguity decorrelation adjustment method which is successfully applied in GPS ambiguities resolution to solve the problem of phase unwrapping according to modified model.On the basis of real data the unwrapping method is tested and reliable results are achieved. |
