摘　　要：本文重点研究了天基光电望远镜对空间目标成像时空间目标、望远镜、太阳之间的相对位置关系。文章分析了天基光电望远镜对空间目标成像时三者的位置关系及其变化对目标光度特征的影响,以及望远镜系统参数对空间目标成像光度特征的影响;给出了太阳直射条件下的空间目标成像条件。通过计算机仿真模拟了考虑目标在望远镜处的光度特征,以及在天基光电望远镜中的成像目标-星空图。研究结果表明,文中方法能有效地描述空间目标在天基光电望远镜中的光度特征。The relative position of space target, telescope and the sun were studied for simulating the imaging of space target on space-based opto-electronic telescope. The influence of the relative position and the parameters of the telescope to the luminant characters of space target imaging in space-based telescope were analyzed. The imaging condition of space-based telescope was presented under the case of the direct radiation of the sun. Considering the target＇s luminant characters, the target-star image was obtained by computer simulation. Our results show that the method proposed in this paper can efficiently describe the luminant characters of the space target.
