摘要

摘要: 为覆盖月基引力波探测的0.1～5 Hz测量频段，进一步提高引力波探测的灵敏度，月基引力波探测方案被提出。在简要介绍引力波数学描述及特性的基础上，对当前已有的几种主要月基引力波探测方案进行了介绍，重点论述了各方案的探测原理、探测灵敏度以及探测目标；将月基探测方案与地面及空间探测方案进行了对比；讨论分析了月基引力波探测方案实施所需要考虑的关键问题，给出了可能的解决方法；讨论分析了月基引力波探测可能的主要噪声源以及对应的影响量级；对月基引力波探测的未来发展进行了展望。

Abstract: To observe the frequency in the range of 0.1 Hz to 5 Hz in lunar-based gravitational-wave detection and improve the sensitivity of gravitational-wave detection, a method of lunar-based gravitational-wave detection was proposed. Based on a brief introduction to the mathematical description and properties of gravitational waves, this paper gave a brief introduction to existing gravitational-wave detectors and compared the lunar-based observatories with the space and Earth-based detectors. Lunar-based detectors that have been proposed, such as Gravitational-wave Lunar Observatories for Cosmology (GLOC), Lunar Gravitational-Wave Antenna (LGWA), etc., are briefly introduced. The critical technique is also discussed and alternative solutions are given. The possible main noise sources and corresponding impact magnitudes for lunar-based gravitational wave detection were discussed. Also, the future development of the lunar-based gravitational wave detection is prospected.
