  • Abstract
    Bistatic synthetic aperture radar with geostationary illuminator (GeoBiSAR) has its own characteristics in terms of geometrical configuration. In this letter, we treat the Earth´s surface as an ellipsoid surface and consider the case of large coherent integration angle and then combine them with the existing methods to determine three key elements describing 2-D resolution for GeoBiSAR and give the generalized resolution calculation formulas for GeoBiSAR. Simulation results verify the validity of the resolution calculation formulas and the related conclusions.
