In this paper, the expression of the geometricdistortion after the along-track motion compensation is derived. Then a method is presented for geometricdistortioncorrection.
对沿航向运动补偿后的几何形变量进行了推导，提出一种校正沿航向运动补偿后几何形变的方法。

Geometriccorrection, is to remove the geometricdistortion of remote sensing images, is an important pre-processing in the application of remote sensing image.
几何校正，就是清除遥感图像中的几何变形，是遥感影像应用的一项重要的前期处理工作。

So it is necessary to correct such images. In this paper I consider the causes of the geometricdistortion in X-ray images, and apply the camera calibration into the X-ray image correction.
