InSAR technology processing and result analysis

InSAR (synthetic aperture radar interferometry) is currently a hot topic that is rapidly evolving thanks to the spectacular results achieved in various fields, especially in the construction of digital elevation models (DEMs) of the Earth´s surface. This paper goes deep into the interference imagery mechanism, and from the application requirement of surveying and mapping, stresses solving InSAR key technology. A phase unwrapping method based on the principle of mean field annealing (MFA) is put forward. Finally, we testing this algorithm on some InSAR data, the result shows that this algorithm can obtain DEM correctly and efficiently. Then we analysis the result and display it through 3D. The display effect looks better.
