中文说明：仿真获取四幅互差半个像素的低分辨率图像，利用反演解析算法重建出一副高分辨率图像，属于亚像元技术或者超分辨率技术。
English Description：
Four low-resolution images with half a pixel difference are obtained by simulation, and a high-resolution image is reconstructed by using inversion analysis algorithm, which belongs to sub-pixel technology or super-resolution technology.
