摘　　要：推导一种新的InSAR编队卫星全零多普勒姿态导引方法。由从星多普勒中心频率,给出了偏航角和俯仰角的解析表达式。仿真结果表明:理论上该法在距离向上可使SAR天线中心完全指向零多普勒线。A new total zero Doppler steering was derived in this paper. The analytic expressions of yaw angle and pitch angle were given out according to the Doppler centroid frequency of the slave satellite. The simulation results showed that the center of SAR antenna could be pointed to zero Doppler line completely by using this method in theory.
