摘要

In this paper, the effect of earth rotation and elliptical orbit on Doppler center frequency in GEO SAR is analyzed, and the close forms of two dimensional yaw and pitch angles for yaw control are analytically obtained in satellite platform coordinate system. Considering the feature of GEO SAR system, the phase scan method is proposed to carry out the high accurate compensation of Doppler center frequency, which can escape from the difficulties of wide angle rotation and reliable stabilization of GEO SAR system. Simulation results show that the above analysis and proposed method is efficient.
