Abstract :
In this paper, we present a practical InSAR data processing flow and analyze the key techniques such as the method to select appropriate interferometric SAR data, coregistration, flat earth phase removal and noise altering of the interferogram, phase unwrapping, conversion from phase to height, geocoding and precise baseline estimation with a special pair of SAR SLC images.
