| 摘 要： | 为了描述航天相机运动过程中随机扰动对成像质量的影响,通过分析相机动态成像过程,得到了存在扰动时相机的调制传递函数,并分别讨论了服从高斯分布和具有正弦规律变化的随机扰动对像质的影响.讨论结果表明,得到的结论与其它文献的分析结果是一致的.因此,对于任意随机扰动,在已知其概率密度的情况下,使用这种方法可以分析它对相机成像质量的影响.

| Abstract: | In order to learn the effect of the random perturbation on imaging quality of the camera during the motion, the process of the dynamic imaging of the camera is analyzed, and the modulation transfer function of the camera is obtained. Then, the influence of the random perturbation, which submits to normal distribution or changes sinusoidally, is studied respectively. The conclusion drawn is consistent with the result of the other literatures. Therefore, the method can be used for analyzing the effect of random perturbation with known probability density on imaging quality. |
