Figure 6. Example of deformation measurement based on a single interferogram. The image is a wrapped interferogram with a
temporal baseline of 11 days, which is superimposed over a SAR amplitude image. Google Earth images are used as background.
The red circle shows an ellipse that includes two phase fringes. The maximum deformation is approximately 3 cm. It is therefore a
relatively fast deformation of 3 cm in 11 days. This result, achieved with just two images, is important especially if the high
commercial price of the TerraSAR-X images is considered.
