介绍了各国研制的星载激光告警系统的发展现状,分析了激光探测告警技术的发展趋势。比较了机载激光告警系统和星载激光告警系统应用背景的不同之处,分析了在外太空环境下对星载激光告警系统一些特殊的要求及其相应的独特的结构和性能。设计了一种基于 CCD 的成像型星载激光告警系统,该系统几乎可以做到整个空间的凝视监视,探测范围不仅是地面,还可以探测天基的反卫星激光武器发出的激光,能提供较为精确的激光来袭方位,有效降低了虚警概率。
The development status of satellite laser warning system developed in various countries is introduced, and the development trend of laser detection and warning technology is analyzed. The difference of application background between airborne laser warning system and spaceborne laser warning system is compared. Some special requirements and corresponding unique structures and performances of spaceborne laser warning system in outer space are analyzed. A CCD-based imaging satellite-based laser warning system is designed. The system can monitor the space almost completely. The detection range is not only the ground, but also the laser emitted by the space-based ASAT laser weapon. Accurate laser attack azimuth, effectively reducing the false alarm probability.
