  • The inherent errors of radar system degrade seriously the performance of Synthetic Aperture Radar(SAR), and these errors should be calibrated to acquire high quality images. In this paper, to the issue of the impact of system errors and non-linearities in FMCW SAR, models of system errors are established, and then the estimation and calibration of system errors are investigated in detail. An improved non-linear high resolution range-Doppler algorithm for FMCW SAR is proposed, according to the requirements of mini-architecture and real-time in FMCM SAR imaging systems. Finally, the feasibility and validity of the presented algorithm is demonstrated with simulation.
