Apparatus and method for compensating SAR image

The present invention is by modeling the object according to whether the geometrical distortion present in the SAR image, we propose a SAR image correction apparatus and method for correcting the SAR image. According to the present invention includes an image distortion determination unit to determine whether the geometric distortion present in the SAR image; If it is determined that the geometric distortion present in the SAR image, object modeling unit for modeling an object included in the SAR image; And by modeling the object and comprising a correction image for correcting the SAR image based on the information obtained.
