摘要: 为了测量卫星姿态不稳定或振动等原因引起的空间相机亚像元像移，设计了基于联合变换相关器的像移测量试验系统。阐述了该方法的数学原理，面阵CCD的安装位置以及输入图像序列的获取方法。根据相关参数确定了试验系统的傅里叶透镜结构和参数，最终设计了试验系统。应用线性插值和像元合并方法获得具有亚像元像移的图像果表明，像移测量的精度不随景物的内容而变化，测量得到的像移误差均方根值0.2pixel。

Abstract: To measure the sub-pixel image motion which is caused by satellite attitude instability or vibration，the joint transform correlator method is designed. The mathematics principles were clarified, the position of matrix CCD on the focal plane and the method of getting input image were presented. Sub-pixel image motion input image which to be tested was got by linear interpolation and pixel combination. The results show that the error does not change with different scene of input images, and the error RMS of 0.2 has been achieved.
