When the MTF is a constant, with the increasing amount of image motion, increasing trend of the width of target strip is weakening. The numerical value is: the image motion is a/3, a/2, a, the corresponding width of target strip is 2a, 2.11a, 2.44a.

• 当MTF一定时，随着像移量的增加目标条带宽度的增加趋势有所减小，具体数值是，当像移量为a/3、a/2、a时，相应的目标条带宽度为2a、2.；11a和2
