摘要：

To reflect the actual shape of the aim from the remote sense image, the space-borne SAR image geometrical rectification theory is researched based on rang-Doppler (R-D) model. The improved R-D solution arithmetic is provided. The whole rectification course is presented using the new arithmetic. The processing speed is enhanced for the new Newton iterative kernel design. The stability performance is advanced because of the iterative course is both at the azimuth and the range directions. Through the experiment with simulation data, it is shown that the new rectification arithmetic is feasible and effective.
