Research on the Near-Earth Asteroid Observation Technology

Abstract

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.
