Location of Mt. Fuji A SAR interferogram (phase difference) contains information on the height, surface deformation, and water vapor distribution. Although the interferometric condition depends on the base line, signal quality, and temporal changes of the target, a good interferogram can provide height information. This figure is the height information derived from the SAR data acquired on Sept. 7, 1995 and Oct. 27, 1995, and overlaid by the amplitude image.
