Abstract :
Anthropogenic features show up as highly coherent objects even in heavily decorrelated interferograms. In order to assess whether the information from such features is still usable, the stability of their phase and coherence is analyzed through a series of interferograms. The results indicate that these features can remain interferometrically stable over several years
