Tutorial Description

SAR interferometry is widely used for the generation of digital elevation models (DEM). The topo-graphic information is derived by exploiting the phase differences of the coherent radar signal from 2 complex-valued SAR images, which are acquired from slightly different orbit positions. After focusing the raw SAR data, three essential steps are the main components of the standard InSAR processing:
1. Co-Registration of the two complex images
2. Interferogram generation and coherence estimation
3. Phase unwrapping
In this tutorial the processing is conducted with the numeric computation language MATLAB. All data and instruction is included in the downloadable ZIP-File.

    I am new to matlab and my work is related to SAR image processing.

    could some one let me know how to execute the code and understand the results. I tried but it is taking too much time.
