Compared with ground radars, space‐borne bistatic radar shows great advantages in higher signal‐to‐noise ratio (SNR) and robuster security. Firstly, this study establishes space‐borne geosynchronous satellite‐low orbiting satellite (GEO‐LEO) space–time two‐dimensional model considering the influence of the rotation of the earth together with the curvature of the earth surface. Then the Doppler trajectory distance dependence of the clutter angle is analysed. Finally, the characteristics of the space‐borne GEO‐LEO model are proved to be beneficial to clutter suppression and ground‐moving targets indication. Simulation results show that the space‐borne GEO‐LEO model has good performance.
