Abstract: When the high resolution remote sensing satellite performs earth observation,various motions of onboard motive components will make the body of satellite produce jitter responses,which affect the image quality.The modeling of jitter responses analysis of remote sensing satellite based on hybrid interface modal synthesis technique is introduced.In addition,a sub-matrix algorithm to increase computational efficiency is presented.Numerical results of jitter analysis of remote sensing satellite under the disturbance of main disturbing resources are also given.
