Investigation on Decorrelation in Processing of D-InSAR

Decorrelation is one of the most difficult problems in the procedure of making the InSAR tech-nique practicable,especially in the processing of D-InSAR.The primary resource inducing decorrelation between the SAR images in D-InSAR is found out by means of quantizing the various resources of decorrelation.Further more,the effective approach of weakening the decorrelation between the SAR images in D-InSAR is put forward on the basis of theoretical analysis and calculation.
