Abstract
Phase unwrapping for SAR Interferometry is one of the barriers for obtaining an operational interferometric SAR system (InSAR).This paper compares three different non linear methods which filter the wrapped phase map. The first method is based on a morphological filter, the second one is a modified median filter and the third is a modified mode filter. The characteristics of these filtering approaches are compared, and the number of residues are calculated after each filtering step.
