提出了一种利用光学卫星五谱段合一多光谱相机影像定量检测卫星颤振，并采用点扩展函数（PSF）空间移变降质模型对影像进行恢复的方法。从时间延迟积分(TDI)电荷耦合器件(CCD)的工作原理出发介绍了卫星颤振对TDICCD影像的影响，提出了利用五谱段合一多光谱相机影像进行卫星颤振定量检测的方法，在颤振检测技术中，利用了稳定的相位辐角相关匹配算法进行波段间配准，算法的匹配精度可达到1/50 pixel。提出了利用PSF空间移变降质模型对影像进行恢复的方法。对资源三号（ZY-3）北京区域的影像进行了实验，用清晰度、细节能量、边缘能量和图像对比度作为客观评价标准。结果表明，恢复后的影像客观指标提高约2倍。同时，用SPOT5同区域正射影像进行了客观指标的横向对比，对比的结果也初步表明能较好地恢复卫星颤振降质。

A method which uses optical satellite multispectral camera with five spectra combinations (MCFS) image in quantitative detection of satellite flutter and point spread function (PSF) space variant blurring model method for flutter compensation are proposed. The working principles of time delay integration (TDI) charge coupled device (CCD) and the influence of satellite flutter on the TDICCD image are introduced. The method of using MCFS image in satellite flutter quantitative detection is proposed. In the flutter detection technology, the robust phase correlation scan angular correlation matching algorithm, which can achieve 1/50 pixel registration precision, is used for registration between bands. The PSF space variant blurring model method is used for image restoration. Beijing regional image from ZY-3 is used in experiments and carried out with definition, details energy, edge energy, and contrast as objective evaluation index. Results show that the objective evaluation index of restoration image is improved about 2 times. At the same time, the same regional orthophoto from SPOT5 is used for compared experiment in objective evaluation index. Comparative results also preliminarily show the evidence of better restoration of satellite flutter reduction.
