星空背景下空间碎片的图像仿真研究

Image Simulation Approach of Targets in Celestial Background

为验证针对空间碎片的探测器的搜索跟踪算法,在对空间碎片的亮度进行详细计算的基础上,提出了利用STK、Matlab、3dmax等多软件平台制作仿真图像,供遥感探测器半物理仿真系统使用的方法。应用表明,这种仿真图像能准确地模拟目标特性变化和空间星空背景,图像产生过程对硬件依赖性小,对整个探测器研制过程中的各个节点所作的仿真验证,都能提供相应的特征图像,通用性好,便于广泛推广。

To prove the reliability of algorithms for target tracking in space scene, a kind of design on hybrid simulation system for remote sensing detectors was proposed with STK, Matlab, 3dmax and some other software platforms producing simulated images. The approach is based on precise target brightness calculation. It proves that the method can simulate target characteristic changes and celestial background accurately. And it has corresponding solutions on various stages of the entire detector developing process. The system depends little on hardware and has widespread availability.
