Simulator for repeat-pass satellite InSAR studies

An interferometric synthetic aperture radar (InSAR) simulator has been developed for testing and optimizing InSAR processing algorithms. With the help of the InSAR simulator, the errors introduced by the InSAR processing algorithms can be isolated and quantitatively detected. The InSAR simulator takes one SAR complex image, and uses a geometry model and noise/error models to create a second image as would be collected from a second SAR antenna. Examples of the application of each module are given, illustrating the performance of the InSAR simulator and the generation of realistic SAR interferograms.
