Satellite Vibration on Image Quality ...

Vibration is one of the important factors affecting the image quality of remote sensing camera for disturbing pixel-matched storage and causing image motion. Analyzing the influence of satellite vibration on the image quality degradation of remote sensing camera will be of great importance in compensating image motion and putting forward the satellite controlling index. Modulation transfer function (MTF) is a major index to evaluate the image quality of optical image system. This paper extends the vibration model from one-dimensional space to two-dimensional space based on the statistical moment theory and the theory in calculating MTF using Line Spread Function (LSF).
