Paper Abstract

In order to improve the characteristic of light-duty of space optical remote sensors and the quality of remote sensing images. A novel means was designed. It is used for remote sensing image restoration in-orbit that based on the modulation transfer function compensation (MTFC). The principle of the modulation transfer function compensation in-orbit was given, and the control system in-orbit of the modulation transfer function compensation was designed. The modulation transfer function curve was obtained by direct measurement in laboratory. The remote sensing image restoration was realized by constrained least square filter. The indexes including mean, standard deviation, edge intensity and others are used to evaluate the quality of remote sensing image restoration. The results show that the evaluation indicators of the restored image are better than the original image, and the MTF at Nyquist frequency is increased to 0.1635 from 0.1501. It totally satisfies the requirement for real-time remote sensing image restoration in-orbit, and significantly improves the image quality.
