Abstract大口径射电望远镜具有极高的系统灵敏度,其建设及运行过程将引入各类电子设备,电磁干扰的有效控制是射电望远镜科学产出的重要保证.本文结合射电天文台址电子设备电磁兼容性要求,分析了现有射电天文领域及其他领域电子设备的主要电磁兼容评估标准及存在的不足,考虑到工程实施的可行性,提出大口径射电望远镜电磁兼容控制方法,涉及台址电子设备所在位置干扰电平限值量化方法、电子设备电磁兼容测量方法和测量要求、屏蔽效能测量方法及测量要求、电子设备电磁兼容控制流程等.该电磁兼容控制方法计划应用于新疆奇台拟建的110 m全向可动射电望远镜(Qi Tai Radio Telescope, QTT),确保QTT拥有良好的电磁兼容性.
Other AbstractThe large-diameter radio telescope has extremely high system sensitivity; however, various electronic devices will be equipped at the constructing and operating process, which will generate electromagnetic interference impacting on radio astronomical observations. Therefore, it is necessary to investigate effective Electromagnetic Compatibility (EMC) control approach. This paper based the EMC requirements of radio astronomy, analyzing the deficiencies and adaptability of the EMC evaluation standards available, considering the feasibility of engineering process and operating management as well, on which an EMC control method for large-diameter radio telescope was proposed, including quantified interference level limits for the electronic equipment, EMC measurement method and shielding effectiveness testing method. This method will be applied to the proposed steerable 110-m aperture radio telescope (Qi Tai Radio Telescope, QTT) in Xinjiang, ensuring that QTT has good EMC performance.
