Abstract :
An algorithm for interferometric phase simulation is presented, which is applicable to spaceborne Interferometric synthetic aperture radar (InSAR). Not only the ideal interferometric phase but also the ideal interferometric factors are generated in this algorithm. A novel method for InSAR performance evaluation was proposed, which is based on ideal interferometric factors. With this method, the errors of each step of InSAR processing can be isolated and analyzed. Furthermore, performance of InSAR processing algorithm can be evaluated.
