葡萄牙空间碎片监测雷达跟踪传感器
A Portuguese radar tracking sensor for Space Debris monitoring
摘要：
空间碎片的增加对空间资产和天基行动构成威胁，并导致共同努力制定应对这种增加的方案。作为葡萄牙国防部领导的葡萄牙空间监视和跟踪项目的一部分，葡萄牙通信研究所正在开发一种新的单基地雷达跟踪传感器rAdio TeLescope pAmpilhosa Serra（ATLAS），该传感器位于葡萄牙Pampilhosa da Serra空间观测站。该系统的工作频率为5.56千兆赫，旨在提供1000公里处截面大于10平方厘米的低地球轨道物体的信息。ErPoB拥有所有必要的设备，以连接到IT-Aveiro的研究和开发团队，并通过葡萄牙SST-PT网络和运营中心连接到欧洲联盟空间监视和跟踪（EU-SST）网络。ATLAS系统具有数字波形合成、采用氮化镓（GaN）技术的功率放大器、全数字信号处理和遵循开放系统（OS）理念并使用商用现货（COTS）技术的高度模块化架构。ATLAS建立了一个现代化的多功能平台，用于快速轻松的开发，研究和创新。整个系统（除了天线和功率放大器）进行了测试，在一个设置与一个主要的反射器的机会，在一个明确的范围。所获得的距离像表明，目标可以很容易地被检测到。这标志着在系统功能测试和更接近能够探测轨道物体的操作系统方面迈出了重要一步。
英文摘要：
The increase in space debris is a threat to space assets, space based-operations and led to a common effort to develop programs for dealing with this increase. As part of the Portuguese Space Surveillance and Tracking (SST) project, led by the Portuguese Ministry of Defense (MoD), the Instituto de Telecomunicações (IT) is developing rAdio TeLescope pAmpilhosa Serra (ATLAS), a new monostatic radar tracking sensor located at the Pampilhosa da Serra Space Observatory (ErPoB), Portugal. The system operates at 5.56 GHz and aims to provide information on objects in low earth orbit (LEO) orbits, with cross sections above 10 cm2 at 1000 km. ErPoB houses all the necessary equipment to connect to the research and development team in IT-Aveiro and to the European Union Space Surveillance and Tracking (EU-SST) network through the Portuguese SST-PT network and operation center. The ATLAS system features digital waveform synthesis, power amplifiers using Gallium Nitride (GaN) technology, fully digital signal processing and a highly modular architecture that follows an Open Systems (OS) philosophy and uses Commercial-Off-The-Shelf (COTS) technologies. ATLAS establishes a modern and versatile platform for fast and easy development, research and innovation. The whole system (except antenna and power amplifiers) was tested in a setup with a major reflector of opportunity at a well defined range. The obtained range profiles show that the target can be easily detected. This marks a major step on the functional testing of the system and on getting closer to an operational system capable of detecting objects in orbit.
