“天基红外系统”高轨卫星构型分析与启示

Configuration analysis and enlightenment of high orbit satellite in the Space-Based Infrared System

“天基红外系统”(SBIRS)是美国空军为取代“国防支援计划”(DSP)预警卫星而设计部署的后续新型导弹预警卫星系统,用于支持导弹预警、导弹防御和作战空间感知等领域,是美国战略战术作战与防御系统的重要组成部分,对国防军事领域具有关键支撑作用。文章根据公开资料,在对SBIRS GEO-3卫星的任务、技术指标和总体能力进行分析的基础上,对其构型设计与特点以及应用的新技术等进行分析和总结,以期为我国的高轨遥感卫星构型设计提供启示。

The Space-Based Infrared System(SBIRS)is a follow-up new missile early warning satellite system designed and deployed by the US Air Force to replace the Defense Support Program(DSP)early warning satellite.It is used to support fields such as missile early warning,missile defense,and battlefield awareness.It is an important part of the US strategic,tactical operations,and defense system,and plays a key role in national defense and military affairs.According to public information and based on the analysis of the mission,technical specifications,general capabilities of the SBIRS GEO-3 satellite,this paper analyzes and summarizes the configuration design,characteristics,and new technological applications of GEO-3 satellite,with an expectation to provide enlightenment for the design of high orbit remote sensing satellites in China.
