An efficient SAR raw signal simulator accounting for antenna attitude variations is presented here, based on the 2-demensional Fourier domain formulation of SAR raw signal in presence of antenna beam pointing errors. It can meet the requirements of InSAR system simulation to deal with the extended scenes. The validity limit is analyzed to show that this algorithm is suit for the simulation of practical systems.
