Abstract

Abstract: In order to simplify the procedure of multi-channel InSAR interferogram simulation and to provide simulated data with adjustable parameters for studies of multi-channel InSAR technology, we propose a multi-channel InSAR interferogram simulation method. The method uses the available DEM and system parameters to calculate the real interferometric phase for each channel, and calculates the coherence caused by various kinds of noise. Then the method utilizes acceptance-rejection method to generate the corresponding phase noise, and adds it to the real interferometric phase. So the needed multi-channel InSAR interferograms are obtained. Analysis and simulation results indicate that the approach is simple and convenient. The approach considers the interferometric phase noise's probability density function strictly, and it provides suitable simulation data sets for the performance comparison and quantitative analysis of various kinds of multi-channel InSAR technique.

Key words: interferometric synthetic aperture radar (InSAR), multi-channel, interferogram simulation, acceptance-rejection method
