一种实现“太空篱笆”系统接收波束形成的方法

摘要

The increase of space debris brings severe threats to spacecraft. The electromagnetic fence system emerges as the times require,such as the US Space Fence system.By analyzing the Space Fence system,an all⁃digital simultaneous multibeam⁃forming method using distributed optical fiber is proposed. The key point of in the process of receiving digital beam⁃forming of Space Fence system is analyzed in detail.The implementation of each module in beam⁃forming system is briefly introduced.The simulation and verification are performed for the formed beam pattern.The above research provides a reference for the scheme design of domestic electromagnetic fence system.%日益增长的空间碎片数量对航天器构成了严重威胁，电磁篱笆系统应运而生，尤以美国的“太空篱笆”系统为代表。在分析“太空篱笆”系统体制的基础上，提出了光纤分布式全数字同时多波束形成方法。详细分析了“太空篱笆”系统接收数字波束形成过程中的关键点，对波束形成架构中各级模块的实现进行了简要介绍，对形成的波束方向图进行了仿真验证，为国内电磁篱笆系统的开发提供参考依据。
