美国“太空篱笆”计划概述

“太空篱笆”计划是美国立足未来国家安全和民事应用需求,为扩大对太空目标的监视范围、增加对太空目标的探测容量、提高对太空目标的探测精度和时效性,特别是探测小型太空目标的需求而提出的一种大型地基雷达系统。该计划试图通过跟踪更多更小的目标,以及取代美国空军1961年以来一直使用的空军太空监视系统来改善空间态势感知能力。文中介绍了“太空篱笆”项目的意图、系统组成及功能,分析了“太空篱笆”项目的关键技术、风险点以及管理方式。

Overview of US Space Fence Program

US space fence program is a large-scale ground-based radar system designed for future national security and civil application, which is presented so as to expand space target surveillance range, increase space target detection volume, boost space target detection accuracy and timeliness, especially detect small space targets. The program is intended to promote space situation awareness capability by means of tracking more and smaller targets as well as taking place of AFSSS being used by USAF since the year 1961. In the paper, purpose, composition, and function of space fence are introduced; key technologies, risk points, and management manner are analyzed.
