Research on laser threat to satellite

Abstract

With the rapid development of laser technology, the potential risk of on orbit satellites being attacked by laser becomes more and more prominent. According to the types of exposed parts of the satellite, the degree of damage and the impact on the satellite function, the vulnerability analysis of the satellite system to laser irradiation was carried out. The results show that the satellite solar array, thermal control components, star sensors and communication antennas are vulnerable to laser attack, and have different degrees of impact on the long-term or short-term operation status of the satellite. Based on the general function module and information logic of the satellite, the satellite laser irradiation threat assessment software is constructed, and the quantitative assessment results of the damage of different components affecting the satellite status under typical space conditions are obtained through settlement, so as to carry out risk assessment and provide reference for formulating defense strategies.
