Abstract :
The high interest to derive digital terrain models from interferometric SAR (InSAR) data stimulated the research to optimally solve the phase unwrapping problem. Several solutions have been proposed. The authors hereby address the phase unwrapping stated as a ill-posed inverse problem and investigate the solutions based on the principle of maximum entropy
