论文摘要
放置在月球轨道或月球侧面表面的射电望远镜对于寻找外星智能（SETI）可能具有很大的价值。这样的望远镜的优点是，它将被月球的主体从射频干扰（RFI）的地面来源所掩盖。尽管RFI可以被其他射电天文学领域识别和忽略，但人与外来生成的无线电发射之间可能的光谱相似性使地球上和地球周围的大量人工无线电发射成为SETI的重要复杂因素。基于月球的望远镜将避免这一挑战。在本文中，我们回顾了有关基于月球的射电天文学的现有文献，讨论了月球SETI的好处，可能的对比度和基于轨道的望远镜设计，并认为在未来十年内，这种举措在技术上和财务上都是科学可行的。
A radio telescope placed in lunar orbit, or on the surface of the Moon's farside, could be of great value to the Search for Extraterrestrial Intelligence (SETI). The advantage of such a telescope is that it would be shielded by the body of the Moon from terrestrial sources of radio frequency interference (RFI). While RFI can be identified and ignored by other fields of radio astronomy, the possible spectral similarity between human and alien-generated radio emission makes the abundance of artificial radio emission on and around the Earth a significant complicating factor for SETI. A Moon-based telescope would avoid this challenge. In this paper, we review existing literature on Moon-based radio astronomy, discuss the benefits of lunar SETI, contrast possible surface- and orbit-based telescope designs, and argue that such initiatives are scientifically feasible, both technically and financially, within the next decade.
