Phase unwrapping is the key step in topographic elevation mapping and reconstruction of three-dimensional terrain model by Interferometric Synthetic Aperture Radar(InSAR).Considering the problem that the existing weighted and unweighted least-squares phase unwrapping results need smoothing,an improved algorithm using phase derivative variance map based on the principle of Least-squares phase unwrapping is proposed.With the real InSAR data,by comparison of the improved algorithm with the existing weighted and unweighted least-squares algorithm,it is verified that the proposed algorithm can effectively deal with the situation that there are too many residues and can get a higher accurate and reliable phase unwrapping results.
