目前采用太阳漫射器的星上定标方法可以实现全视场、全孔径、端点到端点的定标。
At present, the use of a solar diffuser is a desirable approach to the on board absolute radiometric calibration. It provides a full aperture, full field and end to end calibration.
方位向压缩后，将各子孔径数据按时间先后排序拼接、运算，合成出全孔径分辨率图像。
After azimuth compression, the sub-apertures are arrayed and synthesized to offer a full-aperture resolution image.
建立了拼接检测计算的模型。利用最小二乘法计算得到拼接参数，从而恢复大口径光学元件的全孔径波前相位分布。
The calculation model is established based on the theory of the least-square method, and a set of testing equipment is designed.
