According to the imaging principle of these instruments,image motion between two interference images should be one column of pixels when the instruments are in a vertical attitude,and abnormal image motion would arise because of geometric distortion and rotation of the interference images when an attitude incline exists.
根据该类仪器的成像过程,在竖直摄影时,相邻两帧像面干涉图之间的像移量为一列像元;偏离竖直摄影时,由于像面干涉图的几何变形或旋转,会引入非正常像移。
