Abstract

Near-Earth object(NEO)impact with Earth is a major threat to the survival and safety of human beings.Planetary defense is a hot issue in the international community.In order to cope with the impact risk,several space nations and organizations,with the USA as the main strength,have continuously carried out the discovery,tracking,cataloguing and characteristic measurements of NEOs over the past three decades,and have yielded remarkable achievements.For the next step to develop a surveillance and warning system with coordinated space and ground equipment,this paper investigates the current situation of NEO detection technologies,analyses the advantages and features of space-based surveillance,discusses the tasks and schemes of the space-based surveillance system,including the survey simulation technology and the key technologies of infrared space telescopes,which can be used as a reference of developing a surveillance and warning system in China.
