Radar imaging geometry, which performs imaging in the direction of slanting range at the sample time of electromagnetic echo reflection, is quite different from opticalimagery.
雷达是通过接收一定时间间隔内电磁回波成像，它与可见光成像不同。

The effect of the optical system aberrations on the restoration imagery is investigated when the speckle imaging technique is used to process the images of the astronomic telescope.
着重研究了采用斑点成像技术处理天文望远镜图像时，光学系统固定像差对图像恢复结果的影响。
