摘　　要：中国科学院空间中心自行设计搭建了带有大口径望远镜的星载FPI原理样机获取了干涉条纹图像。条纹图像滤波和分割自动化处理已经完成。条纹图像的细化对反演计算中高层大气风场信息的精度至关重要。深入探讨细化概念和细化算法,进行细化条纹滤波修整。采用VC++进行实现,应用效果明显,得到验证。最后,依据原理样机实际情况,探讨中高层大气风速的反演算法,说明其可行性。Center for Space Science and Application Research of CAS have designed and constructed a spaceborne FPI prototype with a large diameter telescope. As a consequence, image of interference fringe was acquired. Visual C ＋ ＋ was adopted to develop the FPI interference fringe image process software and filtering and segmenta- tion algorithms were implemented. As thinning is essential for the accuracy of inverting middle and upper atmos- phere wind, thinning is discussed in details. Moreover, thinning algorithms are negotiated, put into practice and compared. The stripe repairs and maintains are also needed and realized. All the auto-process methods mentioned above have a good experiment result in practice. At last, the feasible inversion principle and algorithm are also interpreted here.
