Abstract

Abstract

This paper deals with the influence of ground fluctuation and roughness on the correlation between distributed Satellites SAR echoes. The model for a rough surface is presented based on the facet theory followed by the analysis of its statistical scattering property. Their influences are shown with several simulation results, where the terrain fluctuation is imitated with a 2-dimention correlative stochastic process，which indicate that the ground fluctuation and roughness deteriorate the correlation if the two satellites are cross-track separated, but have a little influence on the correlation if the two satellites are along-track separated.
