【摘要】：隨著靜止軌道衛(wèi)星影像空間分辨率的大幅度提升,靜止軌道衛(wèi)星的高程修正問題越來越被關(guān)注。根據(jù)新一代靜止軌道衛(wèi)星投影方式和成像模式的特點(diǎn),針對(duì)傳統(tǒng)的迭代搜索算法在某些特殊地面點(diǎn)無法收斂的問題,提出了一種在視向量上直接搜索地面遮擋點(diǎn)的算法,并結(jié)合直接搜索算法穩(wěn)定性強(qiáng)、迭代搜索算法計(jì)算效率高的優(yōu)勢(shì),設(shè)計(jì)了一套靜止軌道衛(wèi)星的高程修正解決方案,通過模擬實(shí)驗(yàn),驗(yàn)證了該方案的有效性。
[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.
