Interferometry process for satellite images SAR

The interferometry radar SAR (INSAR) is used in many application of the earth science, starting with the superposition of the couple of the images radar Single Look complex (SLC) and follows many step of the interferometry process which is presented in this paper. This work concerns the exploitation of radar images SLC of the Algiers area acquired on 03 January and 04 January 1994, the first is taken as master image and the other as slave. We have developed an interferometric process beginning with the implementation of a co-registration algorithm for our images, the elimination of flat-earth phase from the interferogram and at the end we developed a filter in order to minimizing the existing noise to have a good result in the final step of the process which is unwrapping step.
