An efficient and reliable simulation scheme is of great relevance for the interpretation of the real campaign data analysis and the testing of the different interferometric procedures. In a previous work, an interferometric SAR (INSAR) raw signal simulator has been presented and tested versus canonical scenes. In this paper, a simulation over an actual ground site is presented and discussed in order to fully validate the simulator and to show how it can be employed to get some insight into the physical mechanisms governing the interferogram formation. Use of the simulator is finally suggested in order to support a classification scheme based on INSAR coherency maps.
