Abstract :
A new phase unwrapping algorithm for InSAR data processing is presented. This algorithm use multibaseline and multifrequency approach for the joint phase unwrapping of the interferometric images. Before unwrapping the previous smoothing adapted filter should be applied with pivot window sizes. The results of the algorithm operating are presented on four images from ERS-1, ERS-2 tandem over Vesuvio volcano for multibaseline case and on two SIR-C/X images over a Moscow region site for multifrequency case
