摘　　要：数量庞大的近地小行星对地球安全构成了重大潜在威胁,受现阶段小天体观测技术水平限制,仍有大量危险性小行星尚未发现。瞄准我国近地小行星空间观测技术发展需求,通过综合分析国内外近地小行星观测现状及相关技术水平,并结合天/地基小行星观测平台能力对比,从我国近地小天体观测技术基础出发,提出了我国空间红外小行星观测技术方案。采用可见–红外融合探测的技术方案开展小行星搜寻与光谱详察,并通过空间小行星观测平台与地面观测装备网络协同观测,为推动形成我国天体一体化小行星观测体系奠定基础;同时通过对多种小行星撞击地球的防御策略以及小行星利用价值综合分析,为我国开展近地小行星观测、预警、防御等任务提出了初步建议。A huge number of Near-Earth-Asteroids(NEA)pose potential threat to the security of earth. There are also large numbers of hazardous asteroids have not yet been found due to our observation technology. Aiming at the development of near Earth Asteroid space observation technology,this paper analyzes the status and level of NEAs observation technology domestic and overseas,and combining the comparison of the capabilities between the space/ground asteroid observation platform,we promote our scheme of space infrared asteroid observation based on our technology. The scheme plan to research asteroids and get its spectrum information through VIS-IR technology,through cooperative observations with space platform and ground equipment network,and then construction an integrated asteroid observation system of our country. At the same time,through the comprehensive analysis of defense strategies and utilization value of asteroids,some preliminary suggestions about the NEA’s observation,early warning,defense and other missions in china are proposed.
