Simulation of interferogram image for spaceborne SAR system

In interferometric synthetic aperture radar (InSAR) processing, simulation of interferogram is a common practice. It is used as synthetic data to test and validate the whole chain of InSAR processing from the interferogram creation to the DEM reconstruction. Simulators for interferometry, those have been reported in the literature, are developed in very simplified imagery geometry model. In this paper, a interferogram simulator which deal with real radar sensor parameters and orbit data is presented.
