Progress and Prospect of the Lunar-Based Gravitational-Wave Detection

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.
