Developmental State and Technical Features of American Space-Based Infrared Early Warning System

为了学习借鉴先进的技术及经验,加速研究、建造红外天基预警系统,为我国的战略预警建设提供参考,以目前最先进的天基红外预警系统为例,通过对大量文献的分析研究,系统阐述了天基红外卫星星座和红外探测系统的组成、作用和发展.结合相关专业知识分析了现役系统的结构、优点和缺陷,给出了正在实施的天基红外系统(SBIRS)计划及执行情况,归纳指出了其先进的技术特点和强大的预警功能以及我国预警系统存在的差距,反映出建造我国天基红外预警反导系统的紧迫性.

In order to learn advanced technologies and experiences, accelerate researching and setting up the infrared early warning system, and provide reference for our country＇s strategic early warning system construction, this article, taking the current most advanced space-based infrared early warning system as a sample, expounds the configuration, function and development of the space-based infrared satellite constellation and infrared detection systems through reviewing plenty of related technical literatures, and analyzes the composition, advantages and drawbacks of the system on service in terms of learning of the related specialized field. Furthermore, it introduces the plan of space-based infrared system （SBIRS） being carried out and their implementation situation, outlines their advanced technical features and powerful early warning functions as well as the disparities of our early warning systems, thus realizing the urgency of developing our country＇s space-based infrared early warning and missile defense systems.
