Micro-Vibration Analysis and Measurement on High Resolution Remote Sensing Satellites

Because micro-vibration environment of the high resolution remote sensing satellite makes great influence on image quality, it is necessary to design micro-vibration measurement equipment to accurately measure the micro-vibration parameters which impact the CCD imaging quality. The paper proposes a set of template to design the parameters of the micro-vibration on board. Starting from the change of CCD modulation transfer function (MTF) due to the micro-vibration, we can build the model, analyze the relationship of the CCD MTF and the frequency and the amplitude, and then we can determine the minimum of the angular displacement and the angular velocity. Finally design and conclude a set of logical, realizable and optimal template, which can afford facilities for the design on the parameters of measuring micro-vibration on the other high resolution remote sensing satellites.
