Beam synchronization is a key technology for the InSAR system design. The real time antenna beam pointing (ABP) estimation with high precise is necessary to set up and maintain the beam synchronization. In this paper, a method of ABP estimation is presented and its performance is analyzed by using raw data of several space-borne SARs. The simulation experiments of real time ABP estimation on board the spacecraft is given and the results show that the presented method is a robust method for ABP estimation.
