Abstract

In this paper, the impacts of ionospheric scintillation on GEO SAR imaging will be analyzed considering the drifting velocity of irregularities. The drifting velocity effects can originate from the effect on power spectral density (PSD) of phase screen which is used to model the ionospheric scintillation effects. Based on the data from international geomagnetic reference field (IGRF) and satellite tool kit (STK), the GEO SAR imaging simulations for different GEO SAR orbital configurations and positions are carried out. The simulation results demonstrate that the drifting velocity of irregularities will cause the changes of stripe direction and affect the quality of GEO SAR images.
