| Abstract: | Simulation is an important way to carry out interferometric measurement signal processing study of distributed microsatellite SAR. This paper presents a way to simulate complex images and interferogram using facet model, multiplicative noise model, geometric model and signal model of the system. This paper also analyses the correlation of the simulated complex images. Computer simulation realized the simulation method and validated the correlation of complex images. |
