Abstract
It is important to analyze the degradation of the image quality caused by camera vibration in order to determine the tolerance of stabilization in satellite attitude. An improved model for calculating the modulation transfer function (MTF) of a push-broom CCD camera is proposed, and two kinds of experiment systems are constructed to measure the degradation of the MTF caused by vibration. The calculated MTF values with respect to low- and high-frequency vibration agree with the experiment results, indicating that the model is valid for studying the stabilization of satellite attitude.
