空间目标的地基红外观测研究进展

Research Progress on Ground-based Infrared Observations of Space Objects

作为一个新兴的研究方向,空间目标的地基红外观测能够与传统雷达和光学观测形成互补,完善空间监测机制。红外具有宽阔的波段范围和特有的热辐射波段,在光谱分析和白天观测方面蕴藏着更大的发展潜力。近年来美国开始征用大型的红外望远镜,或者通过改造光学望远镜,研究空间目标在红外波段的特性。综述了参与空间目标地基红外观测的望远镜工作状况,以及近10年来空间目标监测在红外巡天、白天观测、测光和光谱分析方面的研究进展,最后对空间目标的地基红外观测研究进行总结与展望。

As a new research field, ground-based infrared observations of space objects may extend the horizons of traditional radar and optical observations, improving the mechanism of space surveillance. With broad wavelength range and thermal radiation bands, infrared band has a greater potential in daytime observations and spectral analysis for development. In recent years, the United States began the exploration of infrared characteristics on space objects, by gaining access to large infrared telescope or transforming optical telescope. In this paper, we give a review of the telescopes participated in the ground-based infrared observations of space objects. And we conclude the research progress of the infrared survey, daytime observations, infrared photometry and spectral analysis in infrared space surveillance for nearly a decade. Finally, a summary and prospects on ground-based infrared observations of space objects will be given.
