天基光电望远镜空间多目标成像模拟技术研究

提出了一种天基光电望远镜对空间多目标成像的模拟方法。首先由卫星轨道参数向量和三维矩阵变换得到卫星在地心赤道坐标系中的坐标矩阵,然后再通过平移、旋转和比例等变换得到卫星及恒星在望远镜中的坐标矩阵,最后即可得到总模拟图。设计了一种应用在天基光电望远镜上的空间多目标成像模拟数据库,并为数据库提供了几种基本的维护管理功能。给出了该数据库的基本设计方法和目标数据实例,提供了1000余颗卫星的相关轨道参数。计算机模拟了天基光电望远镜对空间多目标的成像。仿真结果表明,该方法可有效地模拟天基光电望远镜对空间多目标的成像。

Simulation study of space multi-target imaging for space-based opto-electronic telescope

A method of simulation of space multi-target imaging on a space-based telescope is presented.The coordinate of the multi-target in the geo-center equatorial coordinate is obtained by using 3-D matrix transform and the vector of target parameters.Then,they are transformed to the coordinates of the telescope by using the coordinates translation,rotate transformation and proportion transformation.Consequently,the image is achieved.A database using for simulating multi-target imaging is designed,some basic functions and more than 1000 targets are offered.Examples of targets are shown and some images are simulated.The results indicate that this method can efficiently simulate the image of the space multi-target for a space-based opto-electronic telescope.
