Simulation of Manual Gain Control of Geosynchronous Orbit SAR

To simulate the MGC parameters of GEO SAR, this paper first demonstrate the trajectory and satellite-ground relationship, then, the scattering characteristics of typical natural scenes are established by using the real Digital Elevation Model (DEM) and the physical optics algorithm. The MGC parameters are obtained by the radar equation, the MGC parameters of GEO SAR are finally designed based on the simulation results
