Very impressive results of coherent change detection have been presented for the past ten years. Car tracks or even footprints may be seen on the coherence images as demonstrated by Sandia National Labs with Ka SAR images. Usually these results come from prepared experiments during which all changes are monitored. On the other hand, it has been shown that temporal decorrelation is very high for X band data so the time delay between the acquisition has to be small. The aim of this paper is to assess if coherent change detection might be useful in an urban environment with data taken several days apart.
