The effects of complicated motion error on synthetic aperture radar have been analysed. A precise frequency-division is proposed based on the precise angle-frequency relation. The proposed method completely compensates the residual aperture-variant motion and can be integrated into the traditional image formation algorithms directly. Both the simulated data and real airborne data have been applied to validate this method.
