【摘要】:随着静止轨道卫星影像空间分辨率的大幅度提升,静止轨道卫星的高程修正问题越来越被关注。根据新一代静止轨道卫星投影方式和成像模式的特点,针对传统的迭代搜索算法在某些特殊地面点无法收敛的问题,提出了一种在视向量上直接搜索地面遮挡点的算法,并结合直接搜索算法稳定性强、迭代搜索算法计算效率高的优势,设计了一套静止轨道卫星的高程修正解决方案,通过模拟实验,验证了该方案的有效性。
[Abstract]:With the great improvement of the spatial resolution of geostationary orbit satellite image, more and more attention has been paid to the elevation correction of geostationary orbit satellite. According to the characteristics of the new generation of geostationary orbit satellite projection mode and imaging mode, Aiming at the problem that the traditional iterative search algorithm can not converge at some special ground points, a new algorithm is proposed to directly search the ground occlusion points on the visual vector, and the stability of the algorithm combined with the direct search algorithm is strong. The iterative search algorithm has the advantage of high computational efficiency. A set of elevation correction solutions for geostationary orbit satellites are designed. The effectiveness of the proposed scheme is verified by simulation experiments.
