Paper Abstract

SAR interferometry is a promising tool to generate DEM out of SAR data taken from space. In the state of the arts technology of SAR interferometry, phase unwrapping looks only the problem to be resolved.. In phase noise free environment, phase unwrapping straightforward process to integrate local difference of phase. But this is quite rare case in actual interferometry due to the various phase noise source to distort fringes. In the integration of local phase difference, the effect of the noise is transferred to the neighboring area to jeopardize the estimated DEM. In this paper, I propose an interactive phase unwrapping method which works even under the poor fringe due to noise.
