A New synthesis Algorithm for InSAR phase unwrapping

摘要：

In this paper,we present a new two-dimensional hybrid algorithm for interferometric synthetic aperture radar phase unwrapping. A new synthesis method for InSAR phase unwrapping is proposed by applying the branch-cut and finite element method. The core theory of this method is to identify reliable and unreliable areas. This algorithm makes full use of the advantage of the branch-cut and finite element method. Avoids the phase errors spreading all over the interferogram.Presented experiments on simulated data demonstrate the precision and efficiency of the procedure.
