为解决卫星振动时时间延时积分电荷耦合器件（ TDICCD ）级数的选择问题。采用调制传递函数（MTF）作为评价成像质量的方法，推导了卫星振动时 MTF 与 TDICCD 级数之间的公式，重点研究了在发生线性振动和低频正弦振动时，为使图像质量不产生明显下降的情况下TDICCD级数的选择方法。研究结果表明：在不使图像产生明显的质量下降的情况下，TDICCD 最大允许级数随着振动速率的减小而增大；在同一振动周期下，最大允许振幅随着TDICCD级数的增大而减小；在相同TDICCD级数的情况下，最大允许振幅随着振动周期的增大而增大。

In order to find out the selection method of TDICCD integration stage during satellite vibration, MTF is used as the method of evaluation image quality. First the formula of the relationship between MTF and TDICCD integration stage is given. Then the selection method of TDICCD integration stage during linear vibration and low frequency sine vibration with no perceptible image quality degradation is researched. The result shows that in the condition of no perceptible image quality degradation, as linear vibration velocity increase, the maximum allowable integration stage decreases. In the same low frequency sine vibration period, the maximum allowable integration stage decreases if the amplitude increases.
