How can interferograms be used in geophysics?
In order to correctly interpreter interferograms as geophysical phenomena it is necessary to be able to discriminate some artifacts which cannot be removed and to keep in mind the limits of the techniques. For example tropospheric effects still remain a source of errors in interferometric measurements. They can tough be identified because they produce fringes in all interferograms including a certain date and disappear in interferograms of other dates. Also topographic artifacts can be detected because they appear in the same position in all images.
