In a previous work, an interferometric SAR (INSAR)raw signal simulator has been presented and tested versus canonical scenes. In thispaper, a simulation over an actual ground site is presented and discussed in orderto fully validate the simulator and to show how it can be employed to get someinsight into the physical mechanisms governing the interferogram formation. Use ofthe simulator is finally suggested in order to support a classification scheme basedon INSAR coherency maps.PACS 84.40.Xb – Telemetry: remote control, remote sensing; radar.PACS 91.10.Jf – Topography; geometric observations.
