N2 - The paper propose a new and straightforward derivation method for the two-dimensional attitude control in the satellite local coordinate system in geosynchronous earth orbit (GEO) SAR. The attitude control method considers the earth rotation and elliptical orbit effects, and can comensate the Doppler centroid into zero. Because the GEO SAR platform and the yaw angle are too large, the two-dimnsional phase scanning method is put forward to carr out the high accurate compensation of Doppler centriod, which can avoid the difficulty of rotating and stailizng GEO SAR platform. The simulations validate the correctness of derivation results in this paper.
