本文考虑了地球同步辐射源和低轨卫星接收机双基地合成孔径雷达的椭球几何结构，推导了其地面分辨率公式。通过仿真实验，给出了平面几何条件下与椭球几何条件下的地面分辨率差异，以及LEO接收机沿水平基线沿着方向运动时的前视地面分辨率。得出了几个结论。
The paper considers an ellipsoid geometry for bistatic SAR with geostationary illuminator and LEO receivers, and deduces its ground resolution formula. In simulation experiments, the ground resolution differences between plane geometry case and ellipsoid geometry case are given, and the forward-looking ground resolution is also been given when the LEO receiver moves along the horizontal baseline direction. Several conclusions are drawn.
