A Novel Method for Along-Track Motion Compensation of the Airborne Strip-Map SAR

A method for along-track motion compensation of the airborne strip-map SAR(Syn thetic Aperture Radar) is presented.No complex interpolation is involved in this algorithm,hence the high computational efficiency and the improved image quality are achieved.Theor etical analys is,simulation results and the real data images show that it is of great value in real-time imaging.
