Abstract

We present a new time-domain algorithm for weighted least squares phase unwrapping based on the finite element method. The proposed technique is specially designed for interferometric SAR applications; a noise-robust extension of the algorithm is also investigated. A number of experiments carried out both on simulated patterns and on real ERS-1/ERS-2 data validate the presented technique.
