Zusammenfassung:	According to the present invention, disclosed are an image correction apparatus of an image radar and a system thereof. The image correction apparatus of an image radar comprises a coordinate mapping unit mapping image pixel coordinates of an SAR image obtained from the image radar to earth surface coordinates including the altitude and accurately obtains surface coordinates of the image coordinates regardless of a flight direction and a squint angle, thereby enabling additional precise oscillation compensation of the SAR image. 본 발명에 따르면, 영상 레이더에서 획득한 SAR 영상의 영상 픽셀 좌표를 고도를 포함한 지구 표면 좌표로 맵핑하는 좌표 맵핑부를 포함하여 비행 방향과 스퀸트 각도에 상관없이 정밀하게 영상 좌표의 지표면 좌표를 구하여 SAR 영상의 추가적인 정밀한 요동보상을 할 수 있는 영상 레이더의 영상 보정 장치 및 시스템이 개시된다.
