This work sketches a possible design architecture of a low-frequency radio interferometer located on the lunar surface. The design has evolved from single antenna experiments aimed at the global signal detection of the epoch of reionization (EoR) to the square kilometre array (SKA) which, when complete, will be capable of imaging the highly red-shifted H1-signal from the cosmic dawn through to the EoR. However, due to the opacity of the ionosphere below 10 MHz and the anthropogenic radio-frequency interference, these terrestrial facilities are incapable of detecting pre-ionization signals and the moon becomes an attractive location to build a low-frequency radio interferometer capable of detecting such cosmological signals. Even though there are enormous engineering challenges to overcome, having this scientific facility on the lunar surface also opens up several new exciting possibilities for low-frequency radio astronomy. This article is part of a discussion meeting issue ‘Astronomy from the Moon: the next decades’.

月球干涉仪的低频技术

这项工作描绘了位于月球表面的低频无线电干涉仪的可能设计架构。该设计已经从旨在重新电离时代 (EoR) 的全球信号检测的单天线实验发展到平方公里阵列 (SKA)，完成后，将能够对来自地球的高度红移的 H1 信号进行成像。宇宙黎明到 EoR。然而，由于低于 10 MHz 的电离层不透明和人为射频干扰，这些地面设施无法检测预电离信号，月球成为建造能够检测此类信号的低频无线电干涉仪的有吸引力的地点。宇宙学信号。尽管有巨大的工程挑战需要克服，在月球表面拥有这个科学设施也为低频射电天文学开辟了几个令人兴奋的新可能性。这篇文章是讨论会问题“月球天文学：未来几十年”的一部分。
