Modeling and Simulation of Single-Look Complex Images for Distributed Satelliteborne Interferometric Synthetic Aperture Radar

The significance of modeling and simulating the single-look complex (SLC) images for the distributed satellite borne interferometric synthetic aperture radar (DS-InSAR) system is addressed. Moreover, the simulation modeling for the DS-InSAR SLC images is presented in details, including the geometric model and the radar signal model. Furthermore, an implementation method for DS-InSAR SLC images simulation is proposed, which has the advantage of lower computation loads and higher efficiency compared with the traditional simulation methods. The intensity images and phase interferograms can consequently be generated from the simulated SLC SAR images. Computer simulation results are numerously presented, with the simple conic scenario and the digital elevation model (DEM) of natural terrain. It is straight forward that the simulation results demonstrate the effectiveness of the modeling and simulation method presented in this paper.
