介绍了航空成像系统产生运动模糊图像的机理，建立了运动模糊图像的数学模型，给出了二维运动模糊的点扩散函数，并利用维纳滤波器对航空图像进行了图像模糊去除，通过加窗技术抑制或减小了边缘误差。仿真结果表明，维纳滤波在精度上是有效的，该方法可以达到1个像素的恢复精度。
The mechanism of a motion-blurred image generated from aerial imaging system was introduced.The mathematical model of motion-blurred image was established to give the point spread function of 2-dimensional motion blur,and the Wiener flter was utilized to remove image blur for aerial image.By the window technique,the edge error was restrained or reduced.The simulation results show that the Wiener filtering is effective in precision,which can get the restoration precision of 1 pixel.
