摘要 对于天文研究以及其他频谱用户来说，无线电频谱是一种有限且日益宝贵的资源。保持射电天文学使用的频段尽可能不受不必要的射频干扰 (RFI) 至关重要。频谱管理是实现这一目标的工具之一，其目标包括对其他频谱用户向射电天文学频段发射的 RFI 水平设置监管限制。这涉及与国家、区域和全球多个层面的监管机构和其他频谱用户进行讨论。全球频谱管理框架由国际电信联盟《无线电规则》制定，其中规定，如果干扰使测量的不确定性增加 10%，则对射电天文学有害。 《无线电规则》每三到四年修订一次，在频谱管理方面代表射电天文学界利益的四个组织（IUCAF、CORF、CRAF 和 RAFCAP）积极参与这一过程。这四个组织当前的利益和活动范围广泛，从保护通过监管措施取得的成果，到展望高频使用和巨型射电望远镜使用的未来。
Abstract The radio spectrum is a finite and increasingly precious resource for astronomical research, as well as for other spectrum users. Keeping the frequency bands used for radio astronomy as free as possible of unwanted Radio Frequency Interference (RFI) is crucial. The aim of spectrum management, one of the tools used towards achieving this goal, includes setting regulatory limits on RFI levels emitted by other spectrum users into the radio astronomy frequency bands. This involves discussions with regulatory bodies and other spectrum users at several levels – national, regional and worldwide. The global framework for spectrum management is set by the Radio Regulations of the International Telecommunication Union, which has defined that interference is detrimental to radio astronomy if it increases the uncertainty of a measurement by 10%. The Radio Regulations are revised every three to four years, a process in which four organisations representing the interests of the radio astronomical community in matters of spectrum management (IUCAF, CORF, CRAF and RAFCAP) participate actively. The current interests and activities of these four organisations range from preserving what has been achieved through regulatory measures, to looking far into the future of high frequency use and giant radio telescope use.
